The present disclosure provides a dual-polarized radiating element comprising a feeding arrangement and four dipole arms. The feeding arrangement comprises four slots, which extend from a periphery towards a center of the feeding arrangement and are arranged at regular angular intervals forming a first angular arrangement. The four dipole arms extend outwards from the feeding arrangement and are arranged at regular angular intervals forming a second angular arrangement. The second angular arrangement of the four dipole arms is rotated with respect to the first angular arrangement of the four slots.

The present invention is an antenna provided with: a plurality of radiating parts formed on a base plate; a waveguide tube inside of which radio waves emitted from the radiating parts propagate; a lens having a plurality of curved surfaces having a substantially hyperbolic shape and disposed in an opening of the waveguide tube; and a protruding part formed in a tapered shape between the plurality of radiating parts. The tip of the protruding part is formed at a position lower than an opening surface.

An end-fire antenna for wideband low form factor applications includes a first metal layer, a second metal layer, and a dielectric layer disposed between the first and second metal layers. An open cavity formed in the dielectric layer that is filled with air, the cavity defined by a pair of sidewalls that extend from an aperture of the cavity to a rear wall of the cavity, where the depth of the aperture is defined between the aperture and the rear wall. The cavity is formed by selecting the width of the aperture of the cavity and the depth of the cavity such that the antenna achieves the same gain during operation irrespective of a variation in the thickness of the antenna.

In accordance with one or more embodiments, a guided wave launcher includes an array of antennas configured to generate near field signals. A controller is configured to: select, in response to a first control signal, at least one of a plurality of guided wave modes; and adjust beam steering parameters of the array of antennas according to the selected one(s) of the plurality of guided wave modes. The near field signals combine to induce a guided electromagnetic wave having the selected one(s) of the plurality of guided wave modes, wherein the first guided electromagnetic wave is guided by the transmission medium and propagates along the transmission medium without requiring an electrical return path.
