On the Design of Array Microstrip Antenna with S-Band Frequency for Radar Communication

Abstract

The research aims to design the prototype of microstrip array antenna with S-Band frequency for radar communication. The design methodology has done in several stages. The first stage was conducted the calculation of antenna parameter using manual calculation. The parameters are simulated using Computer Simulation Technology (CST). The optimization processes have done by various parameters are patch width, patch length, and the distance between patches. After finding the best result, the antenna was implemented and the parameter values are tested in the laboratory and compared with the simulation result. The simulation result showed that antenna performance at 3 GHz frequency with 7,07 dB gain, value VSWR 1.0272176, return loss -37,441025, and bandwidth 163,7 MHz the implementation of array microstrip antenna has size 210 × 84.5 mm, with parameter worked on the frequency of 3.04 GHz with gain value 8.6 dB, VSWR 1.068, return loss -29.790, and the bandwidth of 120 MHz. Its showed that the fabrication antenna can work on S-Band frequency as well as the research purpose.
