I need you to find a cheap antenna design software program under $100 that can design Log periodic antennas and pcb log periodic antenna's that would cover the frequency ranges of 140MHz to 3GHz . Similar to CST https://www.cst.com/Applications/Category/Antenna+Design+and+Simulation and an-sof that is accurate to within 0.5DB, that also has antenna simulation capabilities of being accurate to with 0.5DB. I will need you to show me the stats of the software programs that meet mt requirements.
Need you to design and develop a Full Spectrum Antenna Analyzer test equipment with Microsoft windows viewing capability to show all spectrum's data and save all the results to my computer for future analysis. The full spectrum antenna analyzer will cover the full radio spectrum of DC up to 3GHz and be very accurate and fast. See attached Documents for more information. One document is the manual for an Antenna Analyzer I already have, but it does not cover the range I need and it does not have the ability to interface with my laptop computer. You might know of inexpensive equipment that already works for what I need. I also need you to find a cheap antenna design software program similar to CST and AN-SOF that is accurate to within 0...

Overview: I would like a breakout board designed for the Simblee™ Bluetooth® Smart Module RFD77101. There is already one on the market (with design files available), but it is too large for our purposes. As soon as this project is completed, I will be having the boards printed so there is no room for error. Please only show interest in the project if you are sure you can deliver. This is the first step of an ongoing project, so if I'm happy with your work, you will definitely be hired again. Requirements : 1. The board should have the exact same functionality and pinout as the following: Feel free to use that as a guide. 2. I would like the board to be as small as possible. The maximum

I want the design of this to look semi-realistic, the first link shows a picture of a toy with a similar design to what I'm thinking. I want just the face of the robot not the body and have it front facing. In the antenna i want "SEAN" written with the wire. In the left eye I want it to have "IS" as the pupil. In the right eye u want it to have "a" as the pupil. A red triangle nose. In the mouth to have written "ROBOT", see third image for reference. Finally i want antennas coming out the side of his head like in the 2nd image but with the antennas pointing out instead of up. I look forward to seeing your designs!! http://i.ebayimg.com/00/s/NjAwWDYwMA==/z/MH4AAOSwq5lToBVj/$

We need a logo for a new company that is developing antennas. We want it simple in neutral colors; maybe the text should...communication signals. These lines could maybe look good if they were of some dark blue or dark red color. The one line that crosses the letters are thought to coincide with the lines in the letters "K" in "LINKS", and "T" and "E" in "ANTENNA". It should not look like the words are "crossed out", but maybe rather give the impression that the line is behind or "inside" the letters. We would also really like the background of the logo to be transparent, so it could fit on the most background images/colors. We are open to any suggestions on the design. We would be really happ...
Create animated radiation waves on 3 seconds of footage of a cell tower. A still photo is attached. The footage rotates around the tower left to right. The animated waves should not be solid lines but more of an opaque cloud going in all directions form the antenna in the middle of the frame.
Create for me, a connector wifi antenna that sends information online electricity consumption within the power grid connected . The same must feed electricity 120V / 220V . I 'm open to suggestions
Do you have experience in Antenna array, beam formation, linear array, circular array and 4nec2 tool? Drop me a message. I have something to discuss. Thanks.
We want to look at various design ideas for the following: - lightweight, 20 - 40 ft , hollow resin composite, telecom pole - supported by a unique screw pile configuration giving it total stability. - It is "semi-permanent" and can be installed by two men in a matter of hours. - The base area takes up no more than 9sq ft and due to the screw pile requires minimal geo-technical work but would require locate services. - The top of the pole has a wifi mesh-capable radio; - further down is a solar panel; - around the pole near the base is a compact environmental enclosure with back up batteries; and, - an electronics back plane required to manage the various radios, routers, power management, data storage and HVAC necessary to provide the various services, etc...

The breadcrumb menu also needs some work on these pages as it doesn't function as it should. The breadcrumb menu has the following issues: - Displaying category and link as 'Product' instead it should be 'Products' - Does not show sub categories 2) All the 'services' pages on the main menu are currently in a sub folder, these all need to changed.

I have a fairly simple project that I have put together from manufacturers spec sheets and product information. I'm looking for a talented engineer to look it over to find any potential problems and to make suggestions before I send the product to manufacturing. It is a design based around 8-devices Carambola 2 SOC and has a Li-Po charge circuit and simple power distribution, as well as a Ceramic wi-fi antenna. I'll supply my schematics, BOM and links to spec sheets on the components used (3 ICs + the SOC). I created the PCB in Altium, so I could also provide the Altium or Gerber files, if that's of any use.
I 'm working on a project that includes a arduino 1, some sensors and most importantly a solenoid valve (attached link) . This project intend to bring it to a state of production but I need to design a packaging for the entire system which separates the electronics of the valve so that if water comes out of it will not get wet electronics. Modeling should serve to be printed in 3D. Some sensors must be out of the box as soil moisture and temperature . In addition an antenna will be out for the set has gprs connection. Everything must be well sealed because it will be outdoors and must be resistant to rain . Consider that out here will be small solar cells and space for a battery inside Links attached equipment I use

...breakout board/test board for the On Semi AX-SIGFOX SoC chip. You can use the reference design suggested. There is a rough layout from the official development kit here: with further details available after registration (or ask me and I'll send you) This will be used for trials so there aren't many rules. We need at least power and UART broken out into pins and the antenna connection. If you can break out more GPIOs, SPI etc then great. The RF output can go to a PCB edge SMA connector. A bonus would be to add a suitable PCB antenna for 868Mhz such as the one in Texas Instruments Design Note. Please indicate if you're able to do this, it would definitely put you ahead! http://www
We are tracking objects moving through an environment. We have up to 20 RFID antennas (made out of 125khz rfid coils) that objects can pass through. Each object has a unique RFID tag. We need to record every time an object/tag moves through an antenna and record the timestamp and which antenna the object moved through. There are multiple objects (up to 30 unique tags), but it is very unlikely that two pass through the same antenna at precisely the same time. It is ok if the antenna reads from the same tag several times for each pass through, but not tag should be missed. We need sketch + wiring diagram + parts list.
We need to design a enclosure/case but very good looking...similar with a router without antenna, but have something of an apple product finish. I also need consultancy regarding costs since I now nothing about product design/development. We just have an idea in mind, need someone to guide to the right places. Any help appreciated
