Abstract

A multiband hexagonal patch antenna with a compact size of 35 × 30 mm is proposed in this paper using FR4 substrate. The proposed patch antenna consists of four rectangular slots and a circular slot etched into the patch with a coaxial feeding network matched to 50ohms input impedance. The proposed antenna’s performance shows a good multiband operating at 2.40, 5.03 and 8.67 GHz with their return losses at −28, −17, and −22 dB respectively. The comparison between the measurement and simulation results validates the proposed design, satisfying the requirements for wireless communication applications.
