Study and Analysis of Microstrip Patch Array at 12 GHz for 5G Applications

Abstract

This paper presents a study, analysis of microstrip patch arrays for the 5G application. It is
the analysis of a single element, two elements and four elements of microstrip patch designed
at 12 GHz. For better impedance matching, corporate feeding network is used in three
configurations of an array. Microstrip line and patch are etched on RT Duroid 5880
(dielectric constant of 2.2 and a height of 1.56 mm) substrate material. Corporate feeding is
modified and various performance parameters, namely, return loss characteristics,
impedance bandwidth, gain, directivity, and radiation patterned are compared with
conventional corporate feeding. It is observed an improvement in all performance
parameters. From the simulation results of four elements array configuration, it is increased
of 120% gain and directivity as compared to a single element configuration. It is also noticed
that there is an increase of 478% in impedance bandwidth as compared to a single element
configuration. There is decreased of beamwidth in 72% as compared to a single element.
Thus, proposed 4-elements microstrip patch array with modified corporate feeding is
effective candidate for future 5G applications.
