    This paper proposed the techniques for improved gain and radiation patterns include bandwidth enhancement of patch antenna by cutting slots in the ground plane. We proposed three styles of slot cut in the ground plane. There are narrow slot, wide slot, and wide slot with conductor strips. Each style is shown the gain improvement with wideband use in X-band communication systems. Finally, the gain is 6.96 dBi at frequency 10.5 GHz and the average gain from 8 to 10.5 GHz is 4.97 dBi. The radiation pattern shown the low back lobe with good directivity.

    This paper presents the technique for increasing bandwidth of rectangular patch antenna from 0.88 GHz (7.76 - 8.64 GHz) to 6.75 GHz (3.49 - 10.24 GHz). This technique use inset feed patch antenna with modified ground plane for achieved widest bandwidth. We will propose three types of rectangular patch antenna: the simple rectangular patch fed by microstrip line, inset feed rectangular patch and inset feed rectangular patch with modifies ground plane. The final simulation result show that the lower edge of frequency is moved down from 7.76 GHz to 3.49 GHz and the higher edge of frequency is shifted up from 8.64 GHz to 10.24 GHz, which is the one selection for increasing bandwidth of rectangular patch antenna for wideband. Details of the increasing bandwidth of microstrip patch antenna are described, and simulation results for obtained wideband performance are presented by using IE3D Zeland software. © 2008 SICE.
