The advantages of anechoic chambers utilized for antenna measurements, as compared with conventional outdoor antenna test ranges, such as security, interference-free radiation and immunity to weather, are well known. Typical anechoic chambers comprise a shielded enclosure with the internal metallic surfaces covered by absorbing materials, a source antenna to...

A novel CPW-fed rectangle-trapezoid-rectangle shaped monopole antenna composed of a trapezoid and two rectangles is presented. In this context, the flat monopole structure improves the impedance bandwidth and reduces the size of the antenna dramatically. The ultra-wideband (UWB) antenna design plays a role as a filter. The coplanar waveguide...

Sustained growth in wireless communications and greater demands for bandwidth place tremendous pressure on component manufacturers to provide high performance, surface-mount technology (SMT) packaged products. The market is seeking low-cost, standard SMT components for high volume printed circuit board (PCB) assembly flow, in particular for applications such as point-to-point...

The world of telecommunications has experienced an accelerated period of change in recent years. In the past, many terminals such as mobile telephones and PDAs were only capable of transmitting and receiving signals based on a few different standards such as GSM and WCDMA. However, increasing numbers of functions...

In the ongoing race for reduced design costs and faster time to market, simulation efficiency remains the most important factor in electromagnetic field analysis. Simulation efficiency can be determined by the time taken to reach the final design, which is strongly influenced by the level of workflow integration, the...
