A novel dual-band coaperture reflector antenna which sustains the 3.5 GHz band and the 28
GHz band simultaneously is proposed in this article. It allows a switch working mode or dual …

A novel flat lens antenna using double-ring slot element is presented. Compared to those
conventional high-gain antennas, the proposed lens antenna can realize greater flexibility in …

An axially displaced monopulse dual‐reflector antenna operating at W band is proposed in
this study. The antenna configuration consists of a hyperboloid as the subreflector, a …

This work discusses an alternative geometrical optics (GO) technique to synthesize
omnidirectional dual‐reflector antennas with uniform aperture phase distribution together …

This work presents an alternative method for GO synthesis of dual-reflector antennas suited
for omnidirectional coverage. Both reflectors are bodies-of-revolution where a single conic …

A dual X/Ka-band feed system suitable for large Earth Station SATCOM antennas has been
developed. The feed system is suitable for simultaneous four-port operation over both X-and …

In radio astronomy applications, antennas having the highest aperture efficiencies are
requested. In order to meet this request, a reflector shaping program for dual reflector …

A novel broadband reflectarray element composed of two ellipse-like rings is presented.
Compared with those conventional broadband elements, the proposed element can realize …

This work presents a new technique for the geometrical optics (GO) shaping of axisymmetric
dual‐reflector antennas. Both reflectors' generatrices are shaped by the continuous …

This work investigates the synthesis and analysis of omnidirectional dual-reflector antennas.
The body-of-revolution subreflector is generated by a single conic section while the shaped …
