Ultra wide band (UWB) has received a great amount of interest since the decision by the US
Federal Communications Commission (FCC) in February 2002 authorizing the emission of …

We present a theoretical and experimental study of electrodynamics of a planar spiral
superconducting resonator of a finite length. The resonator is made in the form of a monofilar …

A parametric analysis is performed for a wideband Archimedean spiral antenna in
recognition of an emerging concept to integrate RFID along with several applications by …

In the recent years, radio-frequency identification (RFID) technology has been widely
integrated into modern society applications, ranging from barcode successor to retail supply …

This paper describes a directive and ultra wideband antenna with a thickness of lambda/20
at the lowest operating frequency. The low profile of the antenna is obtained by using a high …

An improved meandered spiral antenna with a new semi‐fractal reflector is designed and
fabricated. It is considered as a unidirectional circular polarised broadband antenna having …

获得了这种模型下多辐射源合成场及坡印亭矢量空间分布公式, 并以雷达与诱饵合成场为例给出 …

Increase of functions and improvement of performance required on board aircrafts,
associated to the limited amount of available areas to implement the equipments drive an …

A high impedance surface (HIS) consisting of metallic square patches electrically connected
one to each other with resistors is shown. Tunability of the absorption factor is achieved by …

Antennas installed on aircraft are used for communications as well as for various radio
navigation systems such as direction finders, distance measuring systems, and altimeters …
