A compact and simple structure of ultra-wideband (UWB) frequency selective surface (FSS) single layer was formed to obtain stopband characteristics in this study. The proposed FSS is made of a modified square loop (MSL) structure with an electrical size of 0.15λ0 ×0.15λ0 × 0.041λ0 and is printed on a single side of the dielectric FR4 substrate. To determine the FSS unit cell structure’s behaviour,...
A Cuboid Dielectric Resonator Antenna fed by microstrip feed line is studied. The dielectric resonator of the antenna is made by a material with high dielectric constant ∊r=30. The impedance matching of dielectric resonator can be improved by using a # slot in the ground. In additional, a two elements array is used to enhance the performance of the antenna. This proposed antenna is suitable for long-term...
This study aims to design a new cuboid dielectric resonator antenna (DRA) for LTE Femtocell base stations. The dielectric waveguide model (DWM) was used to carry out the dimension of cuboid dielectric resonator antenna. The dielectric cuboid is based on a high dielectric constant ceramic material, which is ε=30. The feeding structure is dependent on microstrip feed line resides above a FR4 substrate...
An omnidirectional dielectric resonator antenna of cuboid shape is designed for LTE femtocell base station. The dielectric antenna resides above a FR4 substrate, and is fed by a coaxial probe at the center of the antenna. This proposed antenna is appropriate for Long term evolution (LTE) band 7 (2500–2570 MHz, 2620–2690 MHz) and LTE band 38 (2.57–2.62 GHz), the impedance bandwidth is 236 MHz. The...
