Bandwidth Enhancement in Multipatch Microstrip Antenna Array

Free registration required

Executive Summary

Microstrip antennas are used in a wide range of applications, but due to its narrow impedance bandwidth restriction occurs. Microstrip patch antenna is very well known form of printed antenna. Microstrip patch antennas are getting popular in wireless application due to their low profile structure, simple geometry and low fabrication cost. It is a very important element in communications and radar applications since it provides a wide variety of designs, either planar or conformal. Microstrip antennas can be fed by various techniques, besides its advantage of being compact and suitable for antenna array designs. The microstrip antenna generally consists of a radiating element (patch), an intermediate dielectric layer, and a ground plane.
