The strip-fed wideband notched rectangular dielectric resonator antenna is investigated in this paper. By simultaneously exciting the TE111y and TE113y modes of the DRA, a wide impedance bandwidth of 56% can be obtained, which entirely covers the WLAN (2.4-2.48 GHz) and WiMAX (3.4-3.7 GHz) bands. The reflection coefficient, radiation patterns, antenna gain and efficiency of the antenna were studied...
In this letter, a compact differential hollow dielectric resonator antenna (DRA) is investigated. The hollow DRA is fed by two identical conducting strips connected to the outputs of an underlaid 180° hybrid coupler (rat-race). With this compact configuration, loss of the feed network can be minimized and, thus, the differential gain can be made about the same as for the single-ended case. By using...
