Compact Wideband and High Gain Microstrip Patch Antenna for Millimeter Wave Applications

Abstract

In this paper, a novel wideband and high gain microstrip patch antenna for 5G millimeter wave applications is presented. The proposed antenna is designed on a 2-layers RO4350B substrate with a relative permittivity of 3.48 and loss tangent of 0.0031. The proposed design has an impedance bandwidth of 41% at 28 GHz resonant frequency and a maximum gain of 12.5 dB. As shown in Table 1, this design is the simplest 2-layer design that provides the widest bandwidth and has the highest aperture efficiency.
