✦ Synopsis

Abstract

A multiple input multiple output (MIMO) system using three EMC (electromagnetic compatible) chip antennas in a personal digital assistant (PDA) phone is demonstrated. The three EMC chip antennas are mounted at three corners of the system ground plane of the PDA phone and all generate a wide bandwidth covering the wireless local area network (WLAN) operation in the 2.4‐GHz band (2400–2484 MHz). By adding a T‐shaped shorted strip in the proposed MIMO antenna system, large improvements in the isolation (S~12~, S~13~, and S~23~ all less than −20 dB) between any two antennas of the MIMO system are achieved. Detailed effects of the T‐shaped shorted strip on the isolation improvement in the proposed MIMO antenna system are analyzed. Radiation characteristics of the three antennas are also studied. © 2006 Wiley Periodicals, Inc.
