Microstrip Antenna for 5G Communication: Design and Performance Analysis

In this study, a new microstrip antenna is proposed for 5G mobile communication in IEEE802.11ad standard. Hairpin shaped radiating patch is analyzed on three different substrates; FR4, Rogers R054350B and Arlon AD255C. Directivity and bandwidth analyzes based on permittivity are performed to select the most suitable substrate among these three dielectric layers for 60 GHz operating frequency. Rogers RO4350B has 1.17 dBi higher directivity compared to FR-4 and 0.13 dBi smaller directivity gain compared to Arlon AD255C, but offers 2.4 GHz more bandwidth and more compactness than the others. Finally, the proposed antenna is analyzed on four different thickness of Rogers RO4350B and the best performance is observed at 1.2 mm.
