A slot-coupled rectangular dielectric resonator antenna (DRA) operating in the 14–14.5 GHz frequency band is investigated as a possible radiating element for an active integrated antenna of a transmitting phased array. The effectiveness of the resonator shape factor on achieving harmonic tuning is addressed. Simulation results show that the DRA shape factor can be used to provide a fine tuning of the DRA input impedance both at the fundamental frequency and its first harmonics, so synthesizing the proper load for the optimization of the microwave amplifier power-added efficiency (PAE).

A dual frequency Dielectric Resonator antenna for wireless communication applications in the S and C bands with an operating frequency of 2.65GHz and 4.62GHz is presented. The patch is a dielectric material with a high dielectric constant value of 20. A 50Ω strip line is considered as feed and is coupled to the dielectric radiator via the rectangular slot etched in ground plane. The slot etched in ground plane is made so as to facilitate the power form the feed line to the radiator. The overall dimension of the antenna is 100mm×35mm×0.8mm. A dual frequency antenna has been proposed which will be operational at the frequencies of 2.65GHz and 4.62GHz with a gain of 4.42dB and 7.78dB respectively. Low cost FR4 material is been used as the laminate base for the antenna which will act as the dielectric material.

The paper presents a triband circular polarized rectangular dielectric resonator antenna. A single coaxial cable feeds the DRA to a double stub strip on the DRA side. A patch strip coupled to the feed assists in widening the bandwidth of the proposed DRA. The degenerate mode pair TE∂11x and higher-TE∂23x has been excited to achieve CP and enhance the antenna gain. The higher-order mode has been excited using a low-cost simple excitation mechanism without compromising on the size and shape of the DRA. An impedance bandwidth of 48% with a gain ~6–9 dBic was achieved in all resonance frequencies. Additionally, the AR bandwidth of 5.5%, 4.2%, and 2.76% was obtained at three different frequencies. Note that the proposed DRA exhibits a wide beamwidth of 112o, which is good for better signal reception. A comparison between the measured with simulated results shows that the measured results are matched by the simulated result trends.
