A Varactor-tunable Filter with Constant Bandwidth and Loss Compensation

This article presents the basic concept and realization of a bandpass varactor-tunable filter with constant bandwidth and loss compensation. The filter components are based on step-impedance planar resonators, while the equalizing circui...
Varactor-tunable filters attract the attention of microwave specialists due to a number of advantages that can improve the overall performance of communications and radar receivers, as well as measuring equipment. One of the drawbacks of such filters is a considerable variation in bandwidth (BW) and insertion losses (IL) within...

The Design of a Band-rejected Cross Semi-elliptic Monopole Antenna for UWB Applications

A cross semi-elliptic monopole antenna with a band-rejected characteristic is presented and investigated. By embedding four L-shaped slits on the cross semi-elliptic monopole, an antenna with a rejected band from 5.29 to 6.20 GHz can be ...
Planar monopole antennas, with their advantages of low cost and wideband characteristics, are widely used in wireless applications. 1 However, they suffer from distortion of the radiation pattern at higher operating frequencies, which leads to a directional radiation. 2,3 A cross monopole antenna has been implemented to overcome the...
