A Simple Miniaturized Flower Patch Antenna using Meander Lines for X & K Bands

Abstract

This paper proposes an Ultra-Wide Band antenna with multiple bands for satellite and radar communications. A miniaturized meander antenna is proposed, and its design is presented and simulated. The design incorporates a flower type patch antenna and a half planar ground surface using metamaterial. The antenna has a substrate size of 20mm x 20mm with a total thickness of 1.588 mm. By using FR4 epoxy as substrate, antenna resonates at 10.77GHz and 19.00GHz. This paper addresses a simple design methodology for the multiband microstrip patch antenna by using meander lines. This paper also shows the effects on the use of meander lines on the patch antenna. The antenna, so designed suggests a unique structure in which slot is used to propagates multiband frequencies. In this technique, a rectangular MPA is designed, then circular slot is imposed on top of the radiating patch. The results such as return loss, surface charge density, radiation pattern is obtained and discussed. The antenna is simulated on HFSS and results like gain, VSWR, radiation efficiency and radiation pattern are investigated.
