A unique hook-shaped conformal metal strip has been used to excite a cylindrical multilayer dielectric resonator antenna (DRA). By using the proposed unique feed and multi dielectric layers, a broadband circular polarization have been achieved over a bandwidth of ∼9.8% in conjunction with an impedance-matching bandwidth of ∼12.8% at same frequency range. The DRA has been successfully designed and...
This study presents design and analysis of a wideband circularly polarized (CP) cylindrical hollow shaped dielectric resonator antenna (DRA) which has been excited with a roman three (m) shaped feed. The proposed feed has been made-up of five metallic strips, which have been optimized to generate a wideband circular polarization. The proposed antenna offers circular polarization over a bandwidth of...
In this paper a novel Mapping Multiplexing Technique (MMT) is demonstrated. Four channels, (4 × 10 Gbit/s) were successfully multiplexed and transmitted over a single wavelength, which can present a possible transmission rate of 40 Gbit/s per wavelength. The performance of MMT system is examined, with comparison to 40 Gbit/s RZ-OOK, NRZ-OOK and 4-ary techniques. This scheme features a receiver sensitivity...
