Investigation on Harmonic Tuning for Active Ku-Band Rectangular Dielectric Resonator Antennas

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...

Dielectric Resonator Antennas with Band Rejection and Frequency Reconfigurability

In this paper, two types of reconfigurable Dielectric Resonator Antennas (DRAs) are presented. The designs are based on rotating a Dielectric Resonator (DR), placed on the patch of the antenna, using a DC stepper motor connected to the DR to reconfigure the notch frequency, in the first, and the resonance frequency in the second design. The attained results are a UWB DRA with a reconfigurable n...

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 ...

Design and Development of Rectangular Microstrip Array Antennas for X and Ku Band Operation

This paper presents the design and development of two element slot loaded rectangular microstrip array antenna for dual band operation. The dual bands are achieved at X and Ku band of frequencies. Effect of slots of different shapes embedded on the array elements is studied experimentally for enhancing the bandwidth. It is found that by using L-shape complementary slots on the array elements an...
