Project Summary
We are working on GPS anti-jamming system. In this project we will be learning and implementing the different anti-jamming techniques. we will be using microstrip patch antenna and 180 degree hybrid rat race ring coupler and integrate them to anti-jam a GPS signal of L1 band.
Project Objectives
The main idea of this project is to design and develop a Anti jamming system as well as a system which will be compact in size and more efficient the system we are going to develop in this project is through Micro-strip patch antenna array and RF coupler, in this project the other main aim is to design an anti-jam system that will anti-jam signal in RF domain which will need less power to operate unlike other anti jamming systems.
Project Implementation Method
we design a GPS-anti jamming using antenna array. Due to low profile and easy to fabricate, microstrip patch antennas
array combined with hybrid rat race (HRR) couplers provide a simplified method to mitigate the jamming signal
from the original GPS signal. Two microstrip patch antennas
array and two 180 degree HRR couplers are integrated to perform the GPS anti-jamming in the L1 band
(1.575 GHz). where first patch antenna receives a jamming plus GPS signal which is sent towards first coupler’s input port (port 3). While, on port 4, we provide a GPS reference signal to achieve the jamming only signal on difference port (diff port). Furthermore, the second patch antenna’s signal
(jamming plus GPS) is input to the port 3 of second coupler which is also input on port 4 with jamming signal
coming from the first coupler’s diff port. Thus, we achieve the original GPS signal at diff port of coupler 2 easily
by utilizing simple arithmetic i.e., add and subtract, type coupler.
Benefits of the Project
- Low profile
- learn different techniques of anti-jamming
- improvement in communication field
Technical Details of Final Deliverable
By the end of this project we will be able to anti-jam a GPS signal of L1 band at 1.575 GHz frequency. This anti-jamming design can also be used for the traning kit in our university.
Main milestone is to anti jam a GPS Using microstrip Patch antenna array.
