The helical beam antenna has inherent broad-band properties. Over a wide frequency band the pattern shape, circularity of polarization, and terminal impedance are relatively stable. Measured ...

Wide band gap (WBG) materials are more and more used for high frequency and power electronic applications demanding standardized methods for reliability testing and failure analysis. Long term ...

An active calibrated attenuator which can be used with existing medical ultrasound pulse-echo systems is presented. Accurate signal attenuation over a 122-dB range is performed on signals of ...

The objective of this article is to discuss in detail the design procedure for large-order, wide-spurious-free dual-band filters. Two novel contributions are discussed in this context. A zero-volume ...

In this letter, a newly dual-mode composite right-/left-handed (CRLH) resonator with fully symmetrical structure is proposed to design high-order high-temperature superconducting (HTS) dual-band ...

Focusing on the electromagnetic limitations behind wide-band holographic communications, we investigate the embedded element efficiency of infinite regular antenna arrays with non-ideal matching ...

This paper presents the development of a Ka-band Rx phased array designed for SATCOM applications. This dual circularly-polarized antenna array allows to steer its beam up to 70° in all planes, while ...

In this article, an ultra-wideband quad ridge horn antenna, covering two full successive bands, specifically K and Ka bands is introduced. The proposed antenna can carry vertical and horizontal ...

Many advanced industrial applications demand high power amplifiers (HPAs) with ever greater power across a wideband, within a small size, and with high reliability and long life. In addition, for a ...
