Design of a UWB Low Insertion Loss Bandpass Filter with Spurious Response Suppression

This article describes a new ultrawideband (UWB) microstrip bandpass filter based on a dual-mode ring resonator with spur-line structures placed at the input and output ports. This type of filter is characterized by its compact size, sharp rejection, l...
February 8, 2006
Recently, more attention has been paid to applications of ultrawideband (UWB) technology on wireless communication. It offers advantages of decreased cost and increased capabilities, compared with other conventional radio technologies. Standards activities for UWB systems are promoting a global perspective for not only technology but also regulations. UWB has...

Microstrip Line with a Novel Broadband PBG Structure

A new scalariform cross (a cross with a square in the middle) slot structure is proposed for a broadband photonic band-gap (PBG) microstrip line. Compared to other PBG structures of simple geometries, wider frequency stopbands, greater than 40 percent ...
February 8, 2006
Photonic band-gap (PBG) structures were initially proposed in the optical component field. In the microwave field, PBG periodic structures suppress the propagation of electromagnetic waves whose frequencies are within certain bands. They allow shifting the rejected frequency band by simply changing the geometry parameters of the PBG element or...

A Specialized Low Loss 8 dB Coupler

February 8, 2006
A coupler with a through loss of less than 1.45 dB from 5 to 900 MHz was needed in a 75 ? system and only commercial couplers of 10 dB (or more) could offer this low through loss, particularly at the highest frequencies. Unfortunately, another requirement was to produce...

Salvan: Cradle of Wireless

<b>How Marconi Conducted Early Wireless Experiments in the Swiss Alps</b> <br>On September 26, 2003, the IEEE dedicated a “Historical Milestone,” acknowledging some of the first wireless experiments conducted in 1895 by Guglielmo Marconi in Salvan, S...
February 8, 2006
In 1965, inhabitants of Salvan, Switzerland, located above Martigny in the Mont Blanc region, “remembered” that a senior citizen of their village had lived a very unusual experience seventy years before, when he was a young boy. A radio reporter was vacationing nearby, and Maurice Gay-Balmaz, by then 80...
