Abstract—This paper presents a circular ring antenna fed by two perpendicular probes, both of which are placed above the square reflector. The antenna is employed to radiate unidirectional beam for polarization diversity reception. A linear isolator is added to improve the isolation between the two probes. The antenna is proposed for the point-to-point communication of Wireless Local Area Netwo...

DIELECTRIC LEAKY-WAVE ANTENNA ANALYSIS OF ARBITRARY METALLIC SHAPE In this article, the resolution of a dielectric leaky-wave antenna problem of arbitrary metallic strips is presented.

Dielectric lenses can substantially improve antenna parameters, especially the planarity of radiated waves and the antenna gain. The paper deals with their application in millimeter-wave band. The main goal concerns the introduction of characteristics and differences between the most commonly used types of dielectric lens antennas, i.e. elliptic and hyperbolic. Their particular features as well...

This paper presents a new dual-band elliptical dielectric resonator antenna (EDRA). The EDRA is mounted on a ground plane and fed with a rectangular slot exited by a microstrip line. By optimizing the structure parameters, it is possible to obtain more than one excited mode in a limited frequency band. Numerical and measurement results for the radiation patterns of this slot fed EDRA are given ...
