Abstract

This paper presents a multiple-input and multiple-output dual-element planar inverted-F antenna (PIFA) array for broadband operation covering the HIgh PERformance radio Local Area Network/2 (5.2 GHz/5.6 GHz), Wireless Local Area Network (5.2 GHz/5.8 GHz), and the Worldwide Interoperability for Microwave Access (5.5 GHz) bands for the compact wireless communication devices. The antenna dimension is reduced substantially with a miniature ground plane. The PIFA array provides a large bandwidth (670 MHz) and a high isolation between its ports less than −26 dB. The proposed antenna has been analyzed and designed with Ansoft HFSS v.11. Then a prototype was fabricated and tested for its performance in terms of bandwidth, S-parameters, and radiation pattern. A parametric study is made to analyze the effect of different PIFA parameters on the operating frequency and the S-parameters. The diversity performances are evaluated using computer simulation technology microwave studio (CSTMWS). The broadband performance and the high isolation are achieved in both simulation and measurement.
