Performance Analysis and Development of printed circuit Microstrip Patch Antenna with proximity coupled feed at 4.3 GHz (C-band) with linear polarization for Altimeter Application

Abstract

This paper aims at design, develop, optimize and realize a printed circuit Microstrip patch antenna at 4.3 GHz (C-band) with Linear polarization for Altimeter Application with proximity coupled feed method. Antenna is a device which acts as a transducer converting electrical signal to electromagnetic wave and vice-versa during transmission and reception respectively. Development, optimization and testing of high performance Microstrip antenna working in C-band are carried out for Altimeter applications. Various types of antennas are available to meet these requirements. Among these, the printed circuit Microstrip antennas have gained great prominence. With modern wireless method of contact the basic antenna requirements are Gain, Bandwidth, polarization, Size must be low, weight must be low, ease of fabrication. All the requirements mentioned above could be done with the help of printed circuit antennas. Patch antenna is resonant style radiator having narrow bandwidth. Because of its narrow bandwidth this antenna tends to be more efficient and also it tends to be smaller in size which allows the use of this element in antenna arrays and helps in good control of radiation performance. In this project, first we design patch antenna with some design equations and model it in HFSS software.. The simulated results obtained from software are compared with tested fabricated results.
