Design and Performance Analysis of Microstrip Patch Antennas for Airborne Systems

Abstract

Nowadays there is a boundless need for communication between persons and newlineeven between things, using systems onboard like aircraft, cars, ships and satellites. As newlinesignificance, these communications desires antennas fixed on or incorporated in the newlinesurfaces of different vehicles or platforms. In order to confirm appropriate operation newlineof the communication systems it is vital to determine the performance of these newlineantennas. With the development of latest aircraft designs, novel approaches for the newlineintegration of antenna systems have progressed. One important feature of the design newlineof antennas for the future aircraft systems has been the capability to fend for itself in a newlinerapidly changing hazard scenario. Optimizing the design of the antenna characteristics newlinewill lead to substantial improvements in the overall system performance like better newlineaccuracy, superior aerodynamics, and lighter weight. Competent design of aircraft newlinesystems using structurally integrated antenna systems will be capable of multi role newlineoperation. These designs goal towards attempting of the threat, vigorously under newlineelectronic attack. newlinePatch antennas can be numerous geometry, although the main structures newlineconsidered so far are square, rectangle and circular. Aerodynamic drag is the force on newlinean object which resists its motion in air. When mounted on a surface the antennas do newlinenot cause extra aerodynamic drag. Patch antennas are less troubling, occupy newlineminimum space and are not visible to human eye. Due to their electrical and newlinemechanical attractive characteristics, microstrip antennas and arrays are appropriate newlinefor installation in aircrafts. The difficult of hiding multiple antennas and the newlinedegradation of antenna performance due to aerodynamic drag will be completely newlineeliminated by using patch antennas. The Antennas also achieve large beam coverage newlinerange which is required for airborne communication. The choice of structure in terms newlinev newlineof size, shape, orientation, feeding mechanism which may contribute to the better newlineradiation characteristics of the low profile ante
