- W4381300056 abstract "A wideband pattern-diversity cylindrical dielectric resonator antenna (DRA) with high isolation is proposed. Based on the equivalent medium principle and the presented DRA structure of wheel shape, the resonant frequency of the HEM <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>11</sub> <italic xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink><sub>δ</sub></i> mode is increased and combined with that of the HEM <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>12</sub> <italic xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink><sub>δ</sub></i> <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>+1</sub> mode to obtain a wide operation band, both of which are excited by a rectangular slot. In addition, the TM <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>01</sub> <italic xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink><sub>δ</sub></i> mode with wideband impedance matching is well excited by a probe in the presented antenna.

For verification, a prototype of the presented DRA was fabricated and measured. The measured overlapped impedance bandwidth is about 30% (3.08–4.16 GHz), and the port isolation is higher than 30 dB. Besides, the envelope correlation coefficient is very low." @default.
