Design of Dual-band Circular Microstrip Patch Antenna for L-band Military Applications

Abstract

The shorter wavelength of L-band compared to UHF permit users to adopt smaller and more cost effective antenna.A smaller size microstrip antenna is particularly attractive for military use due to greater mobility and ease of camouflage.This paper presents a dual-band circular patch microstrip antenna for L-band military applications.The proposed antenna produced a bandwidth of 1.62 -1.7GHz and 2.74 -2.8GHz.The simulated results are calculated by using lE3D software and MATLAB programming.Further, for the future work, analogous to dielectric relaxation consideration of Cole-Cole diagrams as applied to dielectric materials, a "reactive relaxation concept" will be introduced to present the frequency-dependent characteristics of the circular microstrip antenna.
