Abstract

A wideband printed inverted-F MIMO antenna designed for WiFi applications is presented. The proposed MIMO antenna which consists of two modified inverted-F antenna elements and an isolated structure is designed on a two-layer FR-4 printed circuit board (PCB). The occupied antenna area has the dimensions of 98 mm ∗ 98 mm and the thickness of substrate is 0.8 mm. The functions of antenna’s structure and the effects of some parameters on the antenna performance are discussed in this paper. The designed MIMO antenna system has a wide bandwidth measured more than 0.78 GHz (2.25–3.03 GHz) at the reflection coefficient level below −10 dB. Due to a folded isolated structure, in the whole measured frequency band the mutual coupling is lower than −15 dB, the MIMO antenna has good isolation. On the xy and yz planes the max gain of MIMO antenna can achieve 3 dB. The parameters of simulating and testing are shown that this MIMO antenna has good performance for WiFi applications.
