Title:
ANTENNA FOR A WIRELESS COMMUNICATION DEVICE AND SUCH A DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/226755
Kind Code:
A1
Abstract:
The invention relates to an antenna for a wireless communication device, such as a Wi-Fi access point. The antenna comprises an electrically conductive radiation structure (120) defining a plurality of radially extending radiation slots (121a-f), wherein each of the plurality of radially extending radiating slots (121a-f) has an open outer end at a perimeter (127) of the electrically conductive radiation structure (120) and defines a radiation portion of the electrically conductive radiation structure (120). Moreover, the antenna comprises a feeding network (130) configured to feed a RF signal to the electrically conductive radiation structure (120), wherein the feeding network (130) comprises a plurality of feeding arms (131a-f) configured to feed the RF signal into each of the plurality of radiation portions of the electrically conductive radiation structure (120) for exciting each of the radiation portions to emit electromagnetic waves. The antenna further comprises a grounding structure (101) defining an electrically conductive grounding surface, wherein the electrically conductive grounding surface is spaced from and faces the plurality of radiation portions of the electrically conductive radiation structure (120) for guiding the electromagnetic waves emitted by the plurality of radiation portions. The invention provides an antenna with a low radiating angle and a small build height, which may be advantageously employed, in particular, in an enterprise Wi-Fi access point.
