Design and Analysis of Rectangular Slot Microstrip Patch Antenna for Wi-Fi Application at Millimeter-wave Communication

This study demonstrates the 60 GHz microstrip patch antenna for Wi-Fi application at millimeter wave communication. The proposed antenna has a 5 × 20.5mm2 RT Duriod 5880 substrate with patch which dimensions of 1.90 × 1.49 × 1.59mm
³
, and two rectangular slots that are integrated into the patch and have a dimension of 0.09 × 1.00mm
²
. An additional 0.15 × 0.5mm
²
square-shaped slot has been added to the feed line to increase resonance frequency. A lumped port configuration is applied to estimate the S11 parameter, and the reported design return loss and VSWR are −18.02dB, 1.28 with 5.90dBi of gain. The proposed design may suitable for future generation millimeter wave communication applications
