摘要： An antenna configuration includes two closely spaced antennas each positioned so as to be orthogonally polarized with respect to the other. The antenna configuration increases antenna isolation and reduces electromagnetic coupling between donor side antenna and repeat side antenna. The antennas include printed dipoles connected to respective transceivers through respective baluns to balance the non-symmetrical portions of the antenna feed paths to reduce unwanted radiation therein. Printed features such as chokes and non-symmetrical and non-parallel structures are preferably included in the ground plane of a multi-layer circuit board to reduce or eliminate circulating ground currents.

摘要： A wireless communication node, such as a repeater, including a frequency translating repeater, a physical layer (PHY) repeater, time divisional duplex repeater (TDD) and the like, is configured with a pair of directional patch antennae and an omni-directional antenna. The patch antennae can be selected depending on the orientation of the repeater package to communicate with a station such as an access point or a base station. The omni-directional antenna can be directed toward another station such as a client. The patch antennae and the omni-directional antenna can be orthogonally polarized to increase isolation and reduce electromagnetic coupling. Multiple antennae can be used in multiple-input-multiple-output (MIMO) configurations.

摘要： An antenna array formed on a deformable dielectric material or substrate includes a center element and plurality of radial elements extending from a center hub. In the operative mode, the radial elements are folded upwardly into an approximately vertical position, with the center element at the center of the hub and the radial elements circumferentially surrounding the center element. In one embodiment the center element serves an active element of the antenna array and the radial elements are controllable in a directive or reflective state to effect a directive beam pattern from the antenna array. When not in use, the antenna elements are deformed into a plane and can therefore be integrated into a housing for compact storage. In a phased array embodiment, the center element is absent and the plurality of radial elements, are controllable to steer the antenna beam.
