Printed UWB Antenna Operating Over Multiple Mobile Wireless Standards

In this letter, a spline-shaped ultrawideband (UWB) antenna enabling simultaneous operability over multiple mobile wireless standards-namely the DCS, PCS, UMTS, and ISM bands-is proposed. The antenna is expected to exhibit a good impedance matching …

Synthesis of notched band UWB antennas with a hybrid PSO-spline technique

In this paper, an approach for the synthesis of Ultra-Wideband (UWB) antennas with a notched frequency band is presented. It exploits the effectiveness of a representation based on spline curves to obtain the wideband behavior and the simplicity of …
