Design of Aperture Coupled Fed Micro-Strip Patch Antenna for Wireless Communication

In this paper design and fabrication of microstrip line fed aperture coupled patch antenna is presented at 10 GHz using 0.762 mm and .508 mm thick (epsivr=3.2) substrates. The maximum size of proposed antenna is 35.4 mm by 35.4 mm. The design is optimized by means of parameter-variation studies that have been performed using a 3D electromagnetic simulator. A novel bandwidth enhancing network is described, which is shown to improve the 10-dB bandwidth substantially. The simulated and measured radiation pattern is suited for wireless communication applications. The gain of proposed antenna is 6.21dBi at 10 GHz. The proposed antenna should be useful for X band communication systems, and scaled models for lower frequencies are easy to design
