Abstract
A low profile three element half cylindrical dielectric resonator antenna with Multiple Input Multiple Output (MIMO) application is demonstrated. Antenna element and the feeding scheme is arranged orthogonally in space to minimize mutual coupling between antenna elements. This antenna arrangement offers space diversity with radiation pattern diversity. Proposed antenna is fabricated and experimentally verified. Rogers TMM10 (ε <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">r</inf> = 11.2), a low loss dielectric material is used to fabricate the antenna. Antenna offers a close agreement between simulated and measured results. Proposed antenna element DRA-1 offers 9 – 11.1 GHz, DRA -2 offers 9.2 – 10.6 GHz and DRA -3 offers 8.7 – 11.6 GHz frequency band of operation respectively. It offers 8.3 dBi peak gain at 10 GHz frequency and more than 80% radiation efficiency over the operating frequency range.
