Devices describe herein are configured to radiate radio frequency (RF) energy corresponding to RF signals from a first range of frequencies. The device comprises a patch antenna assembly comprising a microstrip disposed on a printed circuit board and a patch antenna. The device also includes a transmitter configured to generate RF signals from the first range of frequencies at an output of the transmitter and a center feed assembly comprising a waveguide, a lens and the patch antenna assembly disposed in the waveguide. The center feed assembly is configured to radiate from the lens radio frequency (RF) energy corresponding to RF signals from first range of frequencies at a power level greater than the first power level.

Patch antenna-based wideband antenna system

A reflector arrangement is configured for attachment to a wireless communications terminal having a patch antenna. The patch antenna includes a patch radiator in a substantially parallel relationship with a ground plane, and the patch antenna produces a radiation beam of a predetermined beamwidth. The reflector arrangement is configured, when attached to the terminal, to produce a radiation beam of reduced beamwidth relative to the predetermined beamwidth. The reflector arrangement comprises a main reflector and a sub-reflector for reflecting radiation towards the main reflector, and the reflector arrangement is configured such that, when attached to the terminal, the patch antenna acts as a feed antenna for the sub-reflector. The sub-reflector is arranged to collect the radiation from the patch antenna and to reflect the beam towards the main reflector such that the main reflector produces the radiated beam of reduced beamwidth.

Reflector arrangement for attachment to a wireless communications terminal

A patch antenna comprises a patch radiator, at least a first connection point for at least a first radio frequency signal, and at least a first feed structure. The first feed structure is arranged to connect the first connection point to at least two feed points on the patch radiator, a first of the feed points being disposed adjacent to a first edge of the patch radiator, and a second of the feed points being disposed adjacent to a second edge of the patch radiator, the first and second edges being on opposed sides of a central region of the patch radiator. The first feed structure comprises at least a first transmission line arranged to connect the first of the feed points to the second of the feed points, the transmission line being disposed in a substantially parallel relationship to the patch radiator.
