Microstrip Antenna Design with Patch Rectanguler for Primary Surveillance Radar (PSR) L-Band Application

Abstract

This research aims to design an inexpensive primary surveillance radar (PSR) antenna with high efficiency and works on the L-Band frequency by using a microstrip antenna, this antenna has advantages in terms of ease of design, light weight and low production prices. The design of the antenna design is made in a simulation that works at a frequency of 1.3 GHz, the substrate material is made of Fr-4 which has a dielectric constant value (er) of 4.3, while the patch material is made of copper. The antenna has a patch size of 71 x 54 mm array 2x1, while the size of the ground plane is 222 x 124.8 mm. Antenna performance testing is done by looking at S-Parameter simulation and voltage standing wave ratio (VSWR). To get an accurate value at a frequency of 1.3 GHz, the sweep method is applied to the patch by changing the width and length of the patch. From the simulation results we get the S-Parameter value right at the frequency of 1.3 GHz with a return loss value of -35 dB while the value of VSWR of 1.29 indicates the antenna has a high efficiency. This research aims to create an antenna innovation that is based on inexpensive and has high efficiency.
