Design and development of a prism-shaped wideband dielectric resonator antenna

In this paper, design and development of a prism-shaped wideband dielectric resonator antenna is proposed. Three different prism shapes namely, octagonal prism, hexagonal prism, and cuboidal prism, each with two fractal iterations have been simulated and a comparison of return-loss performance has been made. Out of the three proposed antennas, one with optimum simulated bandwidth (BW) was fabricated and tested. The measured results are found in close agreement with the simulated results with an overall bandwidth (-10 dB reference) of 57.5% with respect to 10 GHz resonating frequency.
