Karakterisasi Antena Mikrostrip dengan H-slot untuk Aplikasi Synthetic Aperture Radar Pita X
Characterization of Microstrip Antenna with H-slot for X Band Synthetic Aperture Radar Application
Abstract
A square patch microstrip antenna for X-band synthetic aperture radar has been designed and simulated using proximity coupling method. An H-shaped slot is added at the center of the patch to produce wide bandwidth. Parameter study is carried out during simulation by varying the physical parameters of the antenna to investigate the effect to its performances. Antenna characterization is also performed by comparing the microstrip antenna with and without slot to the conventional microstrip antenna. The final dimensions of the microstrip antenna with H-slot is 11.1mm × 11.1mm. The simulation results show that the proposed antenna yields fractional bandwidth of 34.23% in the range frequency of 7.95GHz to 11.23GHz and peak gain of 4.08dB at the frequency of 10.6GHz.
