The millimetre-wave band offers a large bandwidth and hence can be considered for the high-speed communication in 5G networks. The microstrip patch antennas are highly recommended for 5G wireless application because their inexpensive fabrication, less weight and without any difficulty operated at microwave frequencies. In this survey, a comparative analysis of different configuration of microstrip patch antennas is discussed for both the single-element antenna and an array element. The parameters considered for the analysis of the patch antenna are the return loss, bandwidth, gain, VSWR, etc. This paper highlights an overall research development in millimeter-wave antenna design along with some of the practical considerations such as slotted patches, parasitic patches, split ring resonators, etc., are discussed. Research in the antenna systems is very wide and extensive. The different types encountered for the comparison shall be massive MIMO, beam forming, broad banding, dual and multi-band configurations, reconfigurable type, reduced structure design, linear and circular polarized antennas and so on. |
