Antennas of Circular Waveguides
International Journal of Advanced Computer Science and Applications, 2019 The design of the circular waveguide antenna is proposed for displacement reflector antennas. For them, we use the frequencies of operation so that our waveguide generates the mode, (Transversal Electric), resulting in a high impedance bandwidth. The results obtained from the radiation pattern of the fabricated antenna give excellent results according ...

Wideband Circularly Polarized Vortex Surface Modes on Helically Grooved Metal Wires
IEEE Photonics Journal, 2015 We report the characteristics of a right-handed helically grooved metal wire waveguide. For the helically grooved waveguide, the normal degenerate HE1 spoof surface plasmon polariton (SSPP) mode could be decomposed into two opposite circularly polarized ...
