Abstract

The purpose of this paper is to introduce a compact Ultra-Wideband (UWB) diversity antenna with a very low Envelope Correlation Coefficient (ECC). The design employs a hybrid isolation enhancing and miniaturization technique. The antenna consists of two counter facing monopoles, and is miniaturized by using not only inverted-L stubs but also a Complementary Split Ring Resonator (CSRR) on the ground plane. The added components enhance isolation and enable tighter packing of the antennas. The result is a very compact MIMO array with an overall size of 23 x 29 mm2, that covers the entire UWB spectrum from 3 GHz to 12 GHz, with mutual coupling lower than-15 dB. Moreover, the CSRR unit that acts as a resonator is applied for the first time to suppress the interference of RF currents flowing through the ground plane of this UWB MIMO/diversity antenna. The performance of the fabricated prototype in terms of scattering parameters, broadside (peak) gain, radiation patterns, efficiency and envelope correlation coefficient is presented and discussed.
