Abstract

This letter presents a novel proximity-coupled multiband microstrip patch antenna. The proposed antenna simultaneously operates at Bluetooth (2.4-2.485 GHz), WiMAX (3.3-3.7 GHz), and WLAN (5.15-5.35 and 5.725-5.85 GHz) bands with consistent radiation pattern and uniform gain. The antenna is a two-layer design. A V-shaped patch with a rectangular strip on the top layer is fed by a buried rectangular strip in the middle layer by proximity coupling. Furthermore, resonating parasitic structures in the bottom plane are used to improve the antenna characteristics. The fabricated antenna has a small size of 24 ×27 ×1.6 mm³ on an FR4 substrate.
