A compact wideband Triangular Dielectric Resonator Antenna (TDRA) is analyzed and simulated. Perforations improve bandwidth by letting down the quality factor. The perforations are array of symmetrical circular-shaped slots drilled uniformly on the TDRA. On proposed the optimal size of slots and distance between two consecutive slots, the fundamental modes of the TDRA is preserved. This aids in making...
A compact wideband rectangular dielectric resonator antenna (RDRA) is investigated and presented. Perforations improve bandwidth by lowering down the quality factor. The perforations are an array of symmetrical square-shaped slots drilled uniformly on the RDRA. On choosing the optimal size of slots and distance between two consecutive slots, the fundamental mode of the RDRA is preserved...
In this paper, a strip fed wideband rectangular dielectric resonator antenna using perforations has been proposed. The empirical formula is presented to find the effective dielectric constant after perforation, which comes out to be 23 % lower than the original dielectric constant. This improves Bandwidth (BW) and reduces overall weight of the antenna. Both the modes i.e. TE111 and TE131 are preserved...
