A modified design technique of unidirectional circular patch antenna with parabolic shape ground plane for the application of microwave links is being presented here. Firstly, T-slots are inserted diagonally at the corners of parabolic ground plane in order to increase the directivity. Thereafter, for the further improvement in the directivity as well as gain the ellipse slot in circular patch has also been introduced. The microstrip feed line is given for the proposed unidirectional antenna. The simulation analysis of the antenna is done on software CST Microwave Studio using FR-4 substrate with dielectric constant 4.3. The simulated results and parametric analysis show a good return loss with respect to -10 dB. The radiation pattern characteristic, gain characteristic, VSWR pattern and surface current distribution performance of the antenna have also been compared at different resonate frequencies.Keywords

A compact circular ring antenna with defected ground structure (DGS) has been design for Ultra-Wide Band (UWB) applications. Initially, a circular patch antenna is design by introducing a rectangular DGS structure. Further, slot has been inserted in circular patch to improve the impedance bandwidth. The proposed design covers the frequency range of 2.4-10.4GHz below -10dB. Proposed antenna has design and fabricated on FR-4 substrate having 1.5mm, 4.3 thickness and dielectric constant, respectively. The performance of the designed antenna is analyzing with optimized dimensions in terms of return loss, VSWR, radiation pattern, gain characteristics, group delay and surface current distributions. Further, performance analysis of the proposed antenna has also been compared with existing suggested antennas in literature with compact in size. The fabricated antenna shows a good result with simulations software.Keywords

In this paper, we proposed sixteen channel dense-wavelength-divisionmultiplexing (DWDM) optical transmission system using semiconductor optical amplifiers (SOAs). The SOA amplifiers overcome the attenuation effects of transmitted signal in optical communication systems. To overcome attenuation effects, pre-, post (booster) and In-line SOAs techniques are modeled, analyzed and compared for investigating the performance of DWDM system. The proposed system is designed for 10Gbps network using non-return-tozero (NRZ) modulation format with dispersion compensation fiber (DCF) of length 14kms and a single mode fiber (SMF) of length 70kms using Optisystem7.0 simulator. Performance of designed system is explored and compared in terms of eye shape (eye-diagram), Q-factor and bit error rate (BER) by varying the input power (mw) parameter of CW laser source. It is observed that the In-line SOA amplifier provides the best performance as attenuation compensator for proposed optical transmission systems.Keywords
