Supershaped dielectric resonator antennas

2009 IEEE Antennas and Propagation Society International Symposium, 2009
A family of dielectric resonator antennas, the supershaped DRAs, has been introduced in this communication. These DRAs exhibit wideband matching characteristics and broadside radiation. The cross section of the supershaped DRAs was described by means of a simple analytical expression depending on a set of six real parameters.

Wideband dielectric resonator antenna

Microwave and Optical Technology Letters, 2005
AbstractThis paper presents a new wideband dielectric resonator (DR) antenna. To enhance the bandwidth, two layers of stacked resonators having the same rotational axis of symmetry are used. At the bottom layer, a smaller cylindrical DR is placed concentrically inside a large annular‐ring DR, whereas at the top layer, there is only one cylindrical DR ...

Dielectric Resonator Antenna Loaded with Monopole Antenna

2013 Third International Conference on Advanced Computing and Communication Technologies (ACCT), 2013
A DRA loaded with monopole antenna is proposed in the present work. The metal cap is used to cover the monopole antenna top as well as top of DRA. These designing increase the operative frequency of the antenna. The antenna system resonates at 4.4 GHz. The simulation results of return loss, VSWR, gain and radiation pattern are presented.

Resonant frequency of rectangular dielectric resonator antenna

2017 8th Annual Industrial Automation and Electromechanical Engineering Conference (IEMECON), 2017
In this paper, Rectangular Dielectric Resonator Antenna (RDRA) is investigated theoretically. To investigate the RDRA, the antenna is assumed as a cavity. The wave equation is solved inside the cavity antenna. Simple transcendental equation is given here to predict the resonant frequency of RDRA. One antenna prototype is simulated to verify our theory.
