Performance Enhancement of Microstrip Dipole Antennas Through The Use of Minkowski Frequency Selective Surfaces as A Reflector
Journal Title: IOSR Journal of Electronics and Communication Engineering(IOSR-JECE) - Year 2018, Vol 13, Issue 1
Abstract
In this paper, we present Frequency Selective Surface (FSS)s to be used as reflectors to enhance performances of microstrip dipole antennas throughout their operation bandwidth. Firstly it should be noted that Finite-Integration- based code (CST Microwave Studio) is used for all the modelling, analyses and simulations on FR4(ɛr= 4.4, loss tangent =0.0035). Thus, as a first stage, a broad band microstrip dipole antenna is designed operating between 4GHz-10GHz. In the second stage, the performances of this dipole antenna are investigated using the various FSSs as reflector planes. Finally, the Minkowski unit is found as the most appropriate FSS cell element to enhance significantly in the gain performance of the dipole antenna that is optimized to arise the gain up to 3~4 dB while return loss remains approximately as the same.
