Tx-Rx Lens-Based Satellite-on-the-Move Ka-Band Antenna

Antennas for low-cost Ka-band ground terminal devices

The ever-growing demand for high-speed data links together with the increasing congestion in the traditional microwave spectrum are pushing for the exploitation of higher microwave and millimeter-wave (mm-wave) frequencies, including the so-called Ka band. ...

Electromagnetic inspired acoustic leaky-wave antenna

Juan Ramon Mosig, Hervé Lissek, Seyyed Hussein Seyyed Esfahlani, Sami Driss Karkar

In this article we make an analogy between Electromagnetic and Acoustic transmission-line modelling. Then we use this to introduce acoustic transmission-line metamaterials and finally we introduce the acoustic leaky-wave antenna on the basis of previous st ...

Spherical lens antenna designs with particle swarm optimization

Juan Ramon Mosig, Anja Skrivervik, Ruzica Golubovic, Benjamin Fuchs

A design procedure for spherical lens antennas is described. A particle swarm optimization (PSO) algorithm is coupled to a mode matching technique based on spherical wave expansion to analyze the lens antennas. The proposed methodology is applied to three ...
