Multiple Slot Planar Antenna for X-Band Satellite Mobile Communication

A new design proposed for multiple slot planar antenna for x-band satellite mobile communication. The presented structure is complex and size efficient. One-side is consists of making multiple slots in the main patch, and the back is consists by making a different slots in ground plane. The substrate used is FR-4 with the overall dimensions of 13*14*1.5 cubic millimeters. This structure design is fed by a 50Ω line. This antenna has a low reflection coefficient starting from 4 to 12.6 GHz. The fractional bandwidth of the antenna is 103.6% with stable radiations. The antenna's maximum gain stands at 2.3 dB and the antenna's efficiency stands at 79.6% respectively. It is compact and easy to manufacture. Hence, is can be used for the UWB applications, which includes satellite mobile communication (4/6 and 7/9 GHz), defense communication from 8–12 GHZ (X-band), WiMAX-5.5 GHz and WLAN-5.2/5.8GHz applications.
