A flexible shape generation technique (Surface Contour Shape Generation) is combined with multiobjective evolutionary optimization algorithms in order to synthesize geometrically-diverse dielectric resonator antennas and explore the impact geometry has on relevant performance metrics. It shown that noncanonical shapes can improve gain bandwidth when compared conventional antenna geometries. Pre...

A simple and compact high gain Dielectric Resonator Antenna (DRA) for Ku band frequency operation is proposed in this paper. Ku band is a microwave band having frequency range 12 to 18 GHz. Proposed DRA is based on the principal of the dual resonance and defected ground structure (DGS) having rectangular slot. DRA design resonates at frequency 15.2 GHz and 18 GHz in Ku band frequency operation....

This Letter proposes a T-shaped dielectric resonator (DR) antenna (DRA) to achieve high gain. The proposed comprises cylindrical DR top-loaded by disk, forming DRA that can be fabricated in one go. It is excited the higher-order HEM115 mode. was designed Ku band and validate idea. Its measured peak gain 16.13 dBi at 13.34 GHz, with 10-dB impedance bandwidth of 9.36%. As compared conventional DR...

Abstract:This methodology involves complementary square split ring resonators and a microstrip patch antenna both designed to resonate at same frquency.The proposed antenna is made by using metamaterial reflecting surface to obtain the maximum gain hight of reflecting surface is adjusted.we uses an array of squared split ring resonator (SRR) printed on a low dielectric constant material as the ...

In this paper, a new four element rectangular dielectric resonator antenna (RDRA) for 5.0 GHzWLAN/WiMAX band is proposed. The simulation results for its radiation characteristics and the specific absorption rate (SAR) distribution in a homogenous bio-medium (muscle layer) for different antenna-to-muscle layer spacings are presented at different frequencies in 4.9–5.9 GHz band. The input charact...

In this paper, a wideband dual segment cylindrical dielectric resonator antenna (CDRA) is proposed for 5 GHz WLAN/WiMAX band. The simulation results for the radiation characteristics of the proposed antenna and the absorbed power distribution in a homogenous bio-medium (muscle layer) in direct contact with the proposed CDRA are reported at different frequencies. The specific absorption rate (SA...
