Antenna design jobs
This project is about tuning/matching an antenna ANT-868- SP to an RN2483 wireless module. The schematic and PCB is still in design process, so it would be nice to have someone which tells us what we need to do in the design phase concerning antenna placement and extra components required (milestone 1). After the pcb is ready you will need to tune and match the antenna (soldering skills required plus be able to work with VNA) and provide the final component values. Datasheets and schematic of circuit attached
...Rectenna based on a micro-strip dipole antenna and a microwave rectifier with high conversion efficiency designed at 2.45 GHz. (ISM)Rectenna is a rectified antenna means they are used for harvesting of microwave power, or convert Alternating Current (AC) power to Direct Current (DC) power. . The Rectenna consisting of RF-DC conversion circuits and receiving antennas needs to be designed for high conversion efficiency to realize efficient power transmission. In this paper, the main area of investigation is to design Rectenna circuit by using low pass filter, diode, with patch antenna with the desired frequency lying in that range can be added to get the complete Rectenna circuitry with the use of voltage doubler circuits *SOFTWARE AVAILABLE- ADS(advanced ...
Research and write an article of 1500-2000 words about disconnecting from cable tv (i.e. cutting the cord), getting your TV signal using an antenna and how to view on your TV via a ROKU box, and a HDHomeRun or TabloTV box to watch the channels on your television in very high quality. This article will be used on my blog.
Implement simple radio telescope interferometer antenna array simulation in Matlab, for an arbitrary layout of antennas, at an arbitrary latitude and longitude, for an arbitrary celestial source location, and over an arbitrary period of time. Only very simple GUI required. Almost all mathematics involved is described in links below. See pages 5-26 for details, and for an example of a more limited program in terms of functionality, than what I'm looking for.

We're looking for someone to complete this as soon as possible, so if you can't devote a good deal of time to it, please don't apply. We have a dataset that includes the coordinates (latitude/longitude) of every TV station in the United States. We need someone to use Google Maps to pinpoint these station coordinates, and then build a web app with the following features: 1. The user enters their zipcode 2. The app takes the zipcode and determines its coordinates 3. The app then calculates the distance of nearby tv stations from the zip code coordinates 4. All stations within certain range are displayed for the user (along with metadata for that station), both on the map and in a separate list. 5. The on-page map displays colored circles for each range 6. A couple o...
Design a wireless network with the following requirements and desired features: • The Access points (AP) should be among those which offer the best possible performance with widest possible coverage. They should offer all standard features together with some advanced features suitable for a SOHO of about 60 employees. • Within next 10 months, the company will have two small branch offices. One will be situated 500 meters away, in the south of main office, with 8 employees. The other office with 12 employees will be 3 miles away, situated in the north east of the main office. As there is no wired line infrastructure on those two sites, the company would like to get three sites linked together wirelessly. They heard from media that the WiFi antenna could help so...

I have an RFID reader. YR8600 invelion which is powered by the impinj r2000. I have a raspberry pi that I wish to connect to the serial port on this to read the data. The raspberry pi then needs to send the data to a laravel webserver on the web and insert the rfid number that crossed through the reader's antenna and the timestamp into the laravel database. I need someone to write up the c++ for linux that can read the data from the serial and send it to laravel. Also to build a module for asgardcms which is a laravel based cms that can receive the data and put it in a db. I can supply documentation and information on the impinj r2000 so this can be achieved.

I need someone to help me to setup my raspberry pi computer with an Antenna so I can use it to log Wifi devices and Bluetooth devices close to it and capture the Mac Address. I will also need to have a time stamp when the signal was strongest, this information needs to be stored in a simple database, i.e (MAC address, signal strength, timestamp). This project is very well described here but I need directions how to all of this and if I need some software to collect the data as I want it. I am also doing it on the lates Raspberry and I need an antenna recommendations.
Hi, We are using a TK102 GPS Tracker. The problem we have, it has a weak GSM receiver, as its GSM antenna it a cheap small antenna. The original antenna has only ONE connection connecting the antenna to the tracker PCB board (find ). We want you to tell us how to use a normal external GSM antenna with two connections(). Basically, tell how how to connect an external GSM antenna with two connections to a PCB board that has only 1 connection for GSM. The device tuns on 5v, and battery usage is really important for us. please do not worry about the connections. We will fix them ourselves. You tell us that to do, we will apply the changes.
