Abstract:
1. An interlaced multiband antenna array comprising: a ground plane layer; a first plurality of antenna elements operating in a first continuous frequency range and a second continuous frequency range, the first and second continuous frequency ranges being non-overlapping frequency ranges; a second plurality of antenna elements operating only in the second continuous frequency range; the first plurality and the second plurality of antenna elements arranged on the ground plane layer, and substantially arranged along a first direction with respect to a longitudinal axis of the interlaced multiband antenna array; the first plurality of antenna elements comprising at least eight antenna elements; the second plurality of antenna elements comprising at least four antenna elements; for a majority of the antenna elements of the second plurality of antenna elements, an antenna element of the second plurality of antenna elements is placed between only two antenna elements of the first plurality of antenna elements; a spacing relative to a wavelength of the second continuous frequency range between antenna elements of the second plurality of antenna elements is substantially twice a spacing relative to a wavelength of the first continuous frequency range between antenna elements of the first plurality of antenna elements; each antenna element of the first plurality of antenna elements comprises a plurality of portions electromagnetically coupled both at the first continuous frequency range and at the second continuous frequency range; and an operating frequency of the first continuous frequency range is situated around 900 MHz and an operating frequency of the second continuous frequency range is situated around 1800 MHz.
