Abstract

In this paper, a very compact 6.1GHz band notched printed multiple-input multiple output (MIMO) antenna with the size of only 25×25 mm2 is presented for Ultra-wideband (UWB) applications. Two symmetrical antenna elements are placed in vertical direction which make it easy to realize good diversity performance. The antenna elements are made up of a microstrip feed line and rounded patch. One slit is in the diagonal position, and one slot line is designed to improve the isolation between two orthogonal antenna elements. The 6.1 GHz band notch weakens the probable interference between C band satellite uplink communications and UWB system. Simulated and measured results show that it covers from 3.1 to 12 GHz with S11<-10 dB except rejected band, and the isolation is better than 15 dB in full UWB spectrum.
