the pattern of the antenna can be easily steered without a rotary joint. To demonstrate this concept, a rotary-joint-free H-plane horn antenna is designed, and its performance is predicted using EM ...

Abstract: A wideband circularly polarized (CP) antenna with a conical radiation pattern is investigated ... The probe, which protrudes from a circular ground plane, operates in its fundamental ...

In this paper, a novel broadband high-selectivity stacked filtering antenna with multiple radiation nulls is proposed. The antenna consists of a short-circuited stepped impedance feeding line and two ...

When we filed the application for it with the FCC we showed that the antenna was below ground level, which caused FCC to have to modify their software! The antenna was a single wire suspended a few ...
