A Feed-forward Amplifier Using an Equal Group-delay Signal Cancellation Technique

In this article, new signal cancellers that can match the out-of-phase and group delay of two signal paths simultaneously are proposed. The simultaneous matching of the out-of-phase and group-delay time between two paths can permit broadband signal can...
Modern wireless communication systems utilize digital modulation techniques employing linear complex coding schemes to maximize the channel throughput available capability. Also, a broader channel bandwidth is used for more data transmission than before. In addition, as various communication services, such as cellular phone (IS-95), personal communication service (PCS), IMT-2000...

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...
