A new dual feed antenna element is presented, consisting of a single antenna element with two matched and isolated ports. Matching, bandwidth, and losses are comparable to a standard dipole. The radiation patterns are highly omnidirectional with linear polarisation. The antenna can be implemented both with and without a groundplane.

Terahertz antennas present a different set of challenges to the antenna designer typically striving for very high performance while at the very limit of the chosen fabrication process. Many of the same design techniques used at lower frequencies are still applied, but fabrication constraints impose significant limitations on the type of structure that ...

Proximity feed microstrip antenna
Electronics and Communications in Japan (Part I: Communications), 1986AbstractThe proximity feed microstrip antenna (PMA) fed via a gap enables switching of the polarization with a simple operation of opening or shorting the end of the feed. However, since the PMA is coupled electromagnetically with the feed line printed on the same surface as the antenna, the effect of the feed line on the antenna characteristics is ...
