Ultra-wideband (UWB) phased array antennas are essential for radar, communication, and
Electronic Warfare (EW) applications. Systems can operate over wide-band coverage. The …

Significant effort has been put into the antenna miniaturization. Electrically small antennas
still suffer from various issues, such as a relatively large physical size. Hence, antenna …

This paper presents design and optimization methods for spiral coils utilized for wireless
power transfer in wireless medical implant applications. A theoretical model was examined …

Miniaturization of slow wave antennas exploiting the slow wave enhancement factor is
presented. The printed antennas are periodically loaded with shunt capacitors to slow down …

Historically, antennas and microwave devices relied on isotropic media. This provided for
limited degrees of freedom (one for dielectric and another for magnetic) in the design …

The localization of cable faults is very important for communication systems, power
distribution systems and vehicles. Reflectometry methods are often used to detect and locate …

Fundamental physical limitations restrict an antenna's performance based on its electrical
size. These fundamental limits are of the utmost importance, since the minimum size needed …

A new approach for miniaturizing an ultra-wideband spiral antenna, called the periodic
spiral antenna (PSA), is presented. The combination of-directed meandering of the antenna …

A low-profile, compact spiral antenna with a broadband circularly polarized (CP) response is
presented. The antenna is backed by a ground plane and has unidirectional radiation …

A novel miniaturized and reconfigurable coplanar waveguide (CPW) square-ring slot
antenna is presented in this paper. The miniaturization is achieved via a hybrid approach …
