Abstract-A compact printed and planar Multiple-Input MultipleOutput (MIMO) for Ultra Wideband (UWB) communications is presented. Two circular disc monopole antenna elements constitute the proposed UWB-MIMO antenna operating over the frequency band of 3.2-10.6 GHz. The isolation between the antenna ports has been enhanced to the value of more than 15 dB throughout the frequency band of interest. This enhancement is achieved by taking the advantage of an inverted-Y shaped stub that is being inserted on the ground plane of UWB-MIMO antenna. The insertion of the stub has also facilitated reduction of the size of the antenna, i.e., overall dimensions of the antenna are 40 × 68 mm 2 . The proposed antenna is investigated both numerically and experimentally.

A compact printed ultrawideband (UWB) multipleinput-multiple-output (MIMO)/diversity antenna system (of two elements) with a size of 35 40 mm 2 operating at a frequency range of 3.1-10.6 GHz is proposed. The wideband isolation can be achieved through a tree-like structure on the ground plane. The effectiveness of the tree-like structure is analyzed. Measured S-parameters show that the isolation is better than 16 dB ( 20 dB in most of the band) across the UWB of 3.1-10.6 GHz. The radiation patterns, gain, and envelope correlation coefficient are also measured. The proposed antenna is suitable for some portable MIMO/ diversity applications.

“…Nowadays, broadband and Ultra-wideband (UWB) MIMO antenna represents a very appealing solution for multi-standard device because of the increasing number of operating frequency bands required in mobile terminals. There are several effective methods used in narrowband, which also suit for broadband or UWB to improve isolation, such as adding stub or branch [13][14][15][16] and etching slot in the ground [17][18][19]. Though the method of adding branch has good isolation, it acquires antenna size.…”

Abstract-A new broadband multiple-input multiple-output (MIMO) antenna with good isolation and compact size is proposed. The proposed antenna consists of two G-shaped elements in the upper layer and two inverted L protrude branches and a T slot etched in ground which is used to reduce the mutual coupling. This planar antenna has a bandwidth of 100% with |S 11 | ≤ −10 dB from 2.26 to 6.78 GHz. The value of isolation between the two antenna elements is more than 22.5 dB in the whole band. The experimental results verify the simulations.
