Optimization of Micro strip Patch Antenna with Zig-Zag Slot in Broadband Communication

Abstract

In this paper designed and analysis of the rectangular Microstrip patch antenna for GSM band with frequency band 5.1 GHz. Primarily the designed a conventional unslotted rectangular microstrip patch antenna and measure its different parameters using simulation tools .again introduced a Zig –Zag slotted antenna with dielectric substrate 2.2 and used the centre resonance frequency of 5.1 GHz. The substrate height of the FR4 was 0.787 mm.The comparison results of slotted and unslotted antenna are achieved large bandwidth and gain.The bandwidth of 35.2 % and achieved gain is 7.18 dBi in this poposed designed antenna. To model the probe feed for the microstrip patch we used a lumped port with port impedance equal to 50 ohm. The Zig-Zag antenna developed and its performance are utilized by Zealand IE3D tools. This antenna is used in GSM application and many other communication systems.
