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.
