Rectangular Microstrip Antenna Design and Analysis for Exposure System at 900 MHz with Different Feeding Mechanism

Rahul Dev Mishra, Pramod Kumar Singhal

Abstract


Microstrip antennas widely used in defence applications, in aircrafts and in applications where narrow bandwidth is required. In this work an antenna is designed with 3 different feeding mechanisms. The feeding mechanism is used to provide the path for the flow of current from the source. The three different feeds are Line feed, Quarter wave transformer feed and Inset feed. The rectangular microstrip patch antenna designed at 900 MHz and these 3 types of feeding mechanism is used in same patch and the effect on reflection coefficient, gain, directivity, electric field and magnetic field is observed. The comparison between all parameter is made and the conclusion is derived. This antenna is designed for mounting in the exposure system. Exposure system can be a chamber of plexiglass, wood, in which animals like rats can be placed for certain duration for example one month & two month for observing the effects of radiations on these animals. Hence in this paper same patch is designed using different feeding techniques for best possible results.
Keywords: computer simulation technology (CST), exposure system, fr4 substrate, directivity, gain (IEEE), perfect electric conductor (PEC), quarter wave transformer
