摘要：

A planar antenna array composed of two decoupled multiband wireless wide area network (WWAN) antenna elements for slim mobile phone application is presented and studied in this letter. A wide T-shaped protruded ground is deliberately designed to enhance the impedance matching and decouple the two closely deposed antenna elements. The integrity of the proposed T-shaped decoupling structure allows the reuse of space in between the antenna elements in the real applications. With small size occupation, the proposed antenna array covers two wide operating bands including 824-960 and 1710-2170 MHz, and within a short separating distance it achieves isolation better than 12 dB in the lower band and 15 dB in upper band. A prototype is fabricated, and the array's overall performances are measured and compared to simulated results to validate the proposed solution.
