Performance comparison of microstrip antennas with different frequencies and polarization

Abstract

The research work is based on the analysis of the operation of microstrip antennas for which three different antennas were designed, working in bands ranging from 800 MHz - to 5.5 GHz, checking that the functionality is efficient and that they do not interfere with other frequency bands, There are many advantages that can be taken into consideration when implementing antennas with microstrip technology, such as cost, easy manufacturing, works at high frequencies and sufficient amount of information in the different repositories, to be able to perform the tests, first you have to design the model of the antenna in the software Ansoft Designer, then has to perform the analysis of frequency resonance and radiation pattern, determining the frequency at which it works, as well as the bandwidth and gain of each of them, once verified the proper functioning of the antennas proceed to the manufacture of the antenna, you have to select the material, the thickness of the material, as well as the connectors and the welding points that are made, all these factors influence the optimal operation of the antennas, finally to be able to make the field tests it is necessary to work with a radio spectrum analyzer, the same one generates different signals with different gains and impedances, that will allow to determine in which band of frequencies it is working.
