Abstract

A compact two-port diversity/MIMO antenna with dual band-notch characteristics for ultra wideband (UWB) applications is presented in this paper. The antennas exhibit a good impedance match over frequency band of 3.1 GHz-12 GHz, while exhibiting high isolation. Enhanced isolation is achieved with a decoupling structure having circular slots. The decoupling structure provides isolation of more than 20 dB for whole UWB spectrum. By introducing U-shaped slot in the main radiator and horizontal stubs in ground plane, band-notch characteristic is achieved in proposed MIMO design. Two notches are achieved at 5.150-5.825 GHz (WLAN) and 7.25-7.75 GHz (downlink of X-band satellite). The antenna is miniaturized having dimensions of 22mm × 36mm. The results suggests that the proposed diversity/MIMO antenna design can be suitable for portable UWB applications.
