Compact Wideband Circularly Polarized Dielectric Resonator Antenna With Dielectric Vias
IEEE Antennas and Wireless Propagation Letters, 2022Using dielectric vias, we propose a compact and wideband circularly polarized (CP) dielectric resonator antenna (DRA). The dielectric vias are realized by filling barium strontium titanate nanoparticles with a dielectric constant of 20 into a perforated ...

A dielectric resonator on a microstrip antenna
Proceedings of IEEE Antennas and Propagation Society International Symposium, 2002As long as the resonant frequency of a stand-alone parasitic element is close to but not equal to that of the active microstrip antenna, mutual coupling effects between them could alter the characteristics of the entire system. Satisfactory results are observed when the passive element is placed on top of the patch antenna.

Investigation on dielectric resonator antennas
2017 Third International Conference on Sensing, Signal Processing and Security (ICSSS), 2017The area of wireless communications has been increased from last decade. The success of the second-generation(2G) motivates the development of wideband 3G, 4G, cellular phones and other wireless products and services, including WLAN, local multi-point distributed networks(LMDS), home RF, Bluetooth etc.

2004 14th International Crimean Conference "Microwave and Telecommunication Technology" (IEEE Cat. No.04EX843), 2004
The problem of scattering electromagnetic waves from a radiating aperture by a system of high-Q dielectric resonators (DR) in free space is considered. General expressions are presented for calculating both the amplitudes of coupled oscillations and also the scattered field in the wave zone of the resonator system.

Bidirectional dielectric resonator antenna
2015 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2015A bidirectional dielectric resonator antenna (DRA) is investigated. The rectangular DRA is used, which resonates in its TE 215 y mode. As a demonstration, it is designed to operate at 5.80 GHz for WLAN applications. Its reflection coefficient, radiation pattern, and antenna gain of the bidirectional DRA were simulated and measured.
