Abstract

A dual strip monopole antenna for 2×2 MIMO application is designed using an open strip stub and a parasitic strip, which are respectively employed for band stop filter and pattern diversity. The antenna satisfies the bandwidth requirement of 200 MHz (2.5 to 2.7 GHz) in IEEE 802.16 WiMAX standards, and the in-band isolation between the two monopoles is higher than 20 dB. The proposed design is successfully integrated with SiP (System in Package) and embedded passive components. After system verification, the measured EVM of the WiMAX system is below -30 dB at a 3m distance.
