Design and Analysis of Rectangular and U Slotted Microstrip Patch using Optimization Program in Java for UHF Applications

This paper presents Microstrip antenna in the application for a military band short range radio communication system ultra high frequency(UHF), at a frequency range of 1Ghz - 1.5Ghz. Currently, most military aviation platforms are equipped with UHF communication system for their operational requirements, a design studies in the development for a lightweight, low volume, low profile. Hence, in this paper, bandwidth enhancement techniques such as use of various substrate with low relative dielectric constant (E r), size of antenna as well as U slotted patch antenna with coaxial probe feed technique are discussed and explained using optimization program in java and the genetic algorithm is developed.
