Distributed omni-dual-band antenna system for a Wi-Fi access point
View Patent ↗A distributed broadband, omni-dual-band monopole antenna system for use in a Wi-Fi access point. The distributed omni-dual-band antenna system may include an antenna array that includes 4, 6, or 8 monopole antennas arranged in a circular array fashion along the perimeter of the access point. Each monopole antenna may be associated with a single Wi-Fi radio of the access point, and each of the antennas for the different radios are interleaved in order to provide omni-coverage with minimal distortion; that is, each antenna of the access point is alternated with antennas for different radios. A broadband printed omni-dual-band monopole antenna comprising three horizontal radiating elements arranged in an S-shape and a single vertical radiating element connected to the bottom-most horizontal radiating element is also disclosed.
