Design of A Pentagon Microstrip Antenna for Radar Altimeter Application

Abstract

In the navigational applications, radar and satellite requires a device that is a radar altimeter. The working frequency of this system is 4.2 to 4.3GHz and also requires less weight, low profile, and high gain antennas. The above mentioned application is possible with microstrip antenna as also known as planar antenna. In this paper, the microstrip antennas are designed at 4.3GHz (C-band) in rectangular and circular shape patch antennas in single element and arrays with parasitic elements placed in H-plane coupling. The performance of all these shapes is analyzed in terms of radiation pattern, half power points, and gain and impedance bandwidth in MATLAB. This work extended here with designed in different shapes like Rhombic, Pentagon, Octagon and Edges-12 etc. Further these parameters are simulated in ANSOFT-HFSS TM V9.0 simulator.
