Abstract
A differential-fed hybrid antenna with radiation pattern reconfigurability and broadband feature is investigated in this paper. The antenna consists of an anisotropic dielectric resonator (DR) and a dielectric patch (DP). The antenna is designed to be switched between two states: one state is a dielectric patch antenna (DPA) excited with its TM <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">121</inf> & TM <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">131</inf> modes for broadside radiation, another is a dielectric resonator antenna (DRA) with its <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\text{TE}_{1\delta 1}$</tex> & <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\text{TE}_{12\delta}$</tex> modes for dual directional radiation. Furthermore, the proposed antenna achieves broadband performance due to the multiple resonant modes, which can complete cover D band and E band simultaneously.
