High gain antennas are highly desirable for long-range wireless communication systems. In this paper, a compact, low profile, and high dielectric resonator antenna is proposed, fabricated, experimentally tested, verified. The proposed system has cylindrical with height of 9 mm radius 6.35 as radiating element. sourced slot while the excited rectangular microstrip transmission line. line designe...

The microwave industry has shown increasing interest in electronic ceramic material (ECM) due to its advantages, such as light weight, low cost, low loss, and high dielectric strength. In this paper, simple antennas covered by superstrate layers for 2.30 GHz to 2.50 GHz are proposed. The antennas are compact and have the capability of producing high performance in terms of gain, directivity, an...

The major aim of this paper is to collate the information on application oriented performance of DRA. Here we dominantly discussed on multi functional performance of antenna as a package material along as oscillator and filter and multi aspects of transparent DRA. A glimpse on On-Chip-DRA considering difficulty of the process to encourage the knowledge to overcome discrepancy. A note on Materia...

In this paper, a Rectangular Dielectric Resonator Antenna (RDRA) with a modified feeding line is designed and investigated at 28GHz. The modified feed line is designed to excite the DR with relative permittivity of 10 which contributes to a wide bandwidth operation. The proposed single RDRA has been fabricated and mounted on a RT/Duroid 5880 (εr = 2.2 and tanδ = 0.0009) substrate. The optimized...

Recently, left-handed (LH) metamaterials have been achieved by arranging an array of TE resonant dielectric resonators (DRs) in a cut-off parallel plate waveguide [1], [2]. Since negative permittivity is provided by the TE cut-off background, the DRs only need to generate the required negative permeability in order to realize a LH metamaterial. This configuration provides a more flexible choice...

A simple Dielectric Resonator Antenna (DRA) for X band frequency operation is proposed in this paper. X band is a microwave band lies between frequency range 8 to 12 GHz. In proposed DRA reflector plane is used beneath the microstrip feed line with a small air gap, introduced between feed substrate and reflector plane to reduce the back lobe. Slot coupling is used to excite this DRA. Proposed D...

A compact millimeter-wave (MMW) wideband high-gain antenna is proposed and implemented. The development is based on the design principle of wideband Fabry-Perot resonator antennas (FPRAs). The antenna consists of triple-layer dielectric slabs and a PEC ground, and it is fed by a rectangular waveguide. All slabs are used to form the superstrate that exhibits the increasing reflection phase at th...
