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...

in this paper, using annular resonator we have designed an adding and dropping filter light based ontwo-dimensional photonic crystals. the shape of ring resonator filter adding and dropping that wehave proposed is race track. this filter has a hexagonal lattice structure of silicon bars withrefractive index 3/46 that is located in the context of air with refractive index 1. transmissionefficien...

Polygon-shaped mechanical resonators support modes around their perimeters with very low loss, a promising approach to nanomechanical resonator design for precision force sensing and quantum technologies.

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 ...

Abstract—A novel miniaturized dual-band bandstop filter (DBBSF) is proposed by using the T-shaped defected microstrip structures (DMSs) and the U-shaped defected ground structures (DGSs) in this paper. The layout of the dual-band bandstop resonator (DBBSR) is presented at first. The dual stopbands of the DBBSR can be separately controlled since the mutual coupling of the defected structures is ...
