A Compact Vivaldi Shaped Partially Dielectric Loaded TEM Horn Antenna for UWB Communication

International Journal of Antennas and Propagation, 2014
Ultrawideband (UWB) antennas are of huge demand and Vivaldi antennas as well as the TEM horn antennas are good candidates for UWB applications as they both have relatively simple geometry and high gain over a wide bandwidth.

Reciprocal and non-reciprocal signal manipulation through horn antennas loaded with metamaterial-inspired particles

, 2015
In this contribution, we report our results about the design of metamaterial-inspired particles that can be integrated directly inside horn antennas to perform reciprocal and nonreciprocal manipulation of the received/transmitted signals.

Leaky Horns: A New Paradigm of Developing Electromagnetic Horns Based on Leaky-Wave Structures

Electromagnetic Science
More than one-century history of microwaves has witnessed two seemingly unrelated developments of leaky-wave and horn antennas. While conventional horns cannot be made free from phase error even though the optimum horn criterion is adopted, this problem ...

CP metasurfaced antennas excited by LP sources [PDF]

, 2012
A metasurface which is considered as a polarizer for microwave antennas is proposed in this paper. Preliminary results have shown that circularly polarized (CP) radiation can be obtained from linearly polarized (LP) source antennas with the use of ...
