TL;DR: In this paper, a miniaturized wide beamwidth dielectric resonator antenna is presented to enhance the phase delay between the different positions on the same aperture, where metal patches are attached on the side walls of concave structure to miniaturize the antenna.
Abstract: A miniaturized wide beamwidth dielectric resonator antenna is presented. The wedge-shaped concave structure is introduced to enhance the phase delay between the different positions on the same aperture. Some metal patches are attached on the side walls of concave structure and the top of dielectric resonator antenna to miniaturize the antenna. The resonant frequency of the proposed antenna can be reduced by 26.2%, with excellent half-power beamwidth performance of 165.4° and 179.8° in the E- and H-planes at 24 GHz, respectively.

TL;DR: In this article, a parasitic surface (PS) based wide beam width patch antenna operating at 5 GHz is presented, which is composed of a parasitic ring and six parasitic patches, and it is shown that the PS has little effect on the impedance bandwidth of the patch antenna but can increase the HPBWs by 66.7° (from 85.1° to 151.8°) in the E-plane.
Abstract: A parasitic surface (PS) based wide beam width patch antenna operating at 5 GHz is presented. The half-power beam widths (HPBWs) of the patch antenna are improved by the PS, which is composed of a parasitic ring and six parasitic patches. The parasitic ring is used to increase the HPBW in the E-plane, while the six parasitic patches are used to increase the HPBW in the H-plane. Simulation results show that the PS has little effect on the impedance bandwidth of the patch antenna but can increase the HPBW by 66.7° (from 85.1° to 151.8°) in the E-plane and 88.7° (from 78.9° to 167.6°) in the H-plane at 5 GHz. At the same time, the PS decreases the boresight gain of the patch antenna from 5.42 to 3.06 dBi. Measurement results agree well with the simulation.
