- W4387319218 abstract "A millimeter-wave (mm-wave) dielectric resonator (DR) antenna (DRA) with compact size and wide half-power beamwidth (HPBW) is investigated. This DRA consists of a square DR and a microstrip-coupled slot located beneath the DR which functions as both radiator and DR feeding structure. By making the operating frequency of the slot mode, more exactly, the DR-loaded slot mode, close to the resonance frequency of the (unexcitable) DRA TE <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>112</sub> mode, the DR shows a quasi-TE <sub xmlns:mml=http://www.w3.org/1998/Math/MathML xmlns:xlink=http://www.w3.org/1999/xlink>112</sub> mode field distribution in its interior which radiates as an equivalent magnetic current parallel to the ground plane, thus realizing wide HPBWs of 228° in E-plane and 132° in H-plane without requiring any additional parasitic element. Based on this novel DRA element, an E-plane and an H-plane eight-element linear phased arrays capable of wide-angle beam scanning are further designed, showing a scan range of ±72° with 2.5 dB gain fluctuation and a scan range of ±65° with 0.5 dB gain fluctuation respectively. For experimental demonstration, three feeding networks with fixed phase differences of 0°, 90° and 165° are designed, fabricated, and connected to the proposed E-plane phased array to verify three beam-scanning states of 0°, 32° and 72°, and reasonable agreement between the measured and simulated results is observed." @default.
