Abstract
Antenna assemblies are described herein. In particular, described herein are multi-focal-point antenna devices and compact radio frequency (RF) antenna devices. Any of these assemblies may include a primary feed that includes a single patterned emitting surface from which multiple different beams of RF signals are emitted corresponding to different antenna input feeds each communicating with the patterned antenna emitting surface. The antenna assembly is therefore capable of emitting beams in the same direction having different polarizations using a single primary feed. Also described herein are compact RF antenna devices having a lightpipe that passes through the single patterned emitting surface.
Claims17
A compact radio frequency (RF) antenna device having a lightpipe, the device comprising:
- a base of printed circuit board (PCB) material including a light emitting diode (LED);
- a primary feed held above the PCB comprising a flat emitting surface with an aperture therethrough;
- a lightpipe extending from the LED though the aperture of the primary feed, the lightpipe comprising a stem portion coupled to an emission portion of the LED and extending through the aperture to a cap and an illumination region on or around the cap;
- and
- a radio circuitry on the PCB and coupled to the primary feed, wherein the radio circuitry is configured to transmit RF signals to and from the primary feed.
A compact radio frequency (RF) antenna device having a lightpipe, the device comprising:
- a base of printed circuit board (PCB) material including a light emitting diode (LED);
- a primary feed comprising a sheet of metal having a flat emitting surface with an aperture through the emitting surface, wherein the primary feed is separated from the base by a plurality of antenna input feeds extending from the PCB;
- a lightpipe extending from the LED though the aperture of the primary feed, the lightpipe comprising a stem portion coupled to an emission portion of the LED and extending through the aperture to a cap comprising a translucent illumination region;
- and
- a radio circuitry on the PCB and coupled to the primary feed through the plurality of antenna input feeds, wherein the radio circuitry is configured to transmit RF signals to and from the primary feed through the plurality of antenna input feeds.
