─ In this study, we present an UltraWideband (UWB) monopole antenna with bandnotched function. The proposed antenna is fed by a microstrip line. By using two modified forkshaped slots in the ground plane, bandwidth is increased that provides a wide usable fractional bandwidth of more than 135% (2.82-15.63). In order to achieve band-rejected performance, a cross-ring slot was inserted at the squ...

An H-U-E shaped slotted microstrip antenna with improved bandwidth is presented in this paper. The antenna resonates in the frequency range of (2.0–6.3) GHz with the center frequency of 4.2 GHz. The proposed antenna provides return loss approximately -30 dB. The antenna is fed with coaxial feeding yields an impedance bandwidth of 103.6% and VSWR of less than 1.07. The proposed antenna is simula...

In the present work, a new compact microstrip patch antenna has been proposed in stacked configuration. The characteristics of the antenna are obtained in terms of return loss, gain and bandwidth and are compared with the conventional microstrip patch. It is observed that the new proposed configuration reduces the patch area by 66.34% and at the same time enhances the gain and bandwidth signifi...

Wideband Spectral Broadening Bragg soliton-effect compression and fission are harnessed for the enhancement of supercontinuum spectra. In article number 2100107, Ezgi Sahin, Dawn T. H. Tan, co-workers demonstrate a 4.3x spectral bandwidth enhancement, as well high coherence in generated with picosecond pulses. The results highlight how efficient nonlinear processes gratings may facilitate gener...

In this paper, an active compensation method using two current feedback operational amplifiers (CFOAs) to enhance the bandwidth of finite gain inverting voltage amplifier for use as stand-alone amplifier is presented. It is also shown that the inexpensive passive compensation technique can be applied to composite CFOA based amplifier to improve the phase response in addition to bandwidth enhanc...

In this paper a design of triple band one turn helical antenna without ground plain for center frequency of 2.4 GHz, 3.6 GHz, and 5.4 GHz is discuss. These frequencies are selected such that the antenna radiate for continuous band of 2 GHz to 6.8 GHz frequency with variable gain. The purpose of this novel design is to enhance the gain as well as bandwidth. The triple band is achieved by three c...

This paper describes a dynamic Scheduled Bandwidth Reservation/Fairness MAC control scheme for real-time data (rt-data) service and non-real-time data (nrt-data) service of WLAN condition. It uses a schedule table, which is different from the table of IEEE 802.11, maintained in each station to allocate medium accessing time. It specifies a CYCLE period that includes contention free period (CFP)...

A novel circular micro strip dual band stub loaded antenna is described. The antenna is built with a dielectric constant of (?r =2. 33) with RT/5870 as the substrate material. Due to the effect of stub loading, dual frequency is produced at 1. 88 GHz and 2. 73 GHz respectively for the stub length=17 m. m. With the further increment of stub length, shifting of secondary resonant frequency is pos...
