Dual-Mode Bridge-Shaped Dielectric Resonator Antennas

Investigation of Wideband One-step Stair- Shaped Dielectric Resonator Antennas

The one-step stair-shaped dielectric resonator antennas (DRAs) with a circular cross-section are studied theoretically and experimentally in this paper. The reasons why the one-step stairshaped DRAs have a wideband performance have been investigated. It is shown in this paper that the modes excited in the one-step stairshaped DRA with circular cross-section can be regarded as pseudo HEM111 and ...

Probe-Fed Rectangular Dielectric Resonator Antennas,Theoretical Modeling and Experiments

A Rectangular Dielectric Resonator Antenna (RDRA) is theoretically analyzed using the Conventional Dielectric Waveguide Model (CDWM), numerically simulated using the High Frequency Structure Simulator (HFSS) based on the Finite Element Method (FEM) software package and experimentally investigated with the consideration of the fundamental mode TE 111. Antenna parameters under investigation inclu...

Fractal Bandpass Filter Using Y-shaped Dual-Mode Resonator for C-Band Receiver (Research Note)

In this study, a fractal, Y-shaped dual-mode resonator bandpass filter (BPF) with input-output cross-coupling is introduced. A parallel-coupling feed structure with a cross coupling has been used to generate two transmission zeroes (TZs) near the lower and upper cutoff frequency that can effectively improve the passband edge selectivity. Also, a fractal shaped based on conventional diamond and ...
