Abstract

An antenna arrangement made of four similar compact dual-band chip antennas is proposed for uses on WLAN access point devices. The antenna are placed at corners of a small printed circuit board that emulates a WLAN base station. The antenna comprises a feeding line, a clearance region and a chip with a slotted patch. The volume occupied by each antenna chip is 8.5 × 3 × 1.6 mm³ only. Antenna diversity is achieved with a combination of spatial diversity and pattern diversity. Simulation and measurement results demonstrate good isolation performance among antennas. Proposed antenna configuration can also be applied to WLAN devices with the MIMO feature.
