In some embodiments, an antenna may include a plurality of reflectarray tiles and a frame including a plurality of frame elements coupled electrically and mechanically. The frame may be configured to conform to a shape of a surface. Each frame element may be configured to receive one of the plurality of reflectarray tiles. In some aspects, the plurality of reflectarray tiles may be illuminated directly or indirectly by a feed.

Conformal multi-band antenna structure

In some embodiments, an apparatus may include a conductive planar structure having a plurality of antenna elements and a plurality of cutout portions. The plurality of cutout portions may define a combiner circuit including an output interface and including a combiner circuit coupled between each of the plurality of antenna elements and the output interface.

Low cost antenna array and methods of manufacture

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.

Integrated, closely spaced, high isolation, printed dipoles

A wireless mobile handset includes an antenna array. The antenna array includes a passive element disposed on a first portion of a dielectric substrate and an active element disposed on a second portion of the dielectric substrate. The passive element is configured to operate in a reflective mode to produce a bi-directional radiation pattern.

Mobile communication handset with adaptive antenna array

An antenna apparatus, which can increase capacity in a cellular communication system or Wireless Local Area Network (WLAN), such as an 802.11 network, operates in conjunction with a mobile subscriber unit or client station. At least one antenna element is active and located within multiple passive antenna elements. The passive antenna elements are coupled to selectable impedance components for phase control of re-radiated RF signals. Various techniques for determining the phase of each antenna element are supported to enable the antenna apparatus to direct an antenna beam pattern toward a base station or access point with maximum gain, and, consequently, maximum signal-to-noise ratio. By directionally receiving and transmitting signals, multipath fading is greatly reduced as well as intercell interference.

Adaptive antenna for use in wireless communication systems

A wireless handset including an antenna array. The antenna array includes an active antenna element and two passive antenna elements. The active and passive antenna elements are arranged to form a triangle with a vertex. The vertex includes a vertex angle and the active antenna element is disposed at the vertex. The vertex angle is between 90 degrees and 180 degrees.

Aperiodic array antenna

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.

Directional antenna configuration for TDD repeater

A stacked patch antenna including a distributed reactive network proximity feed, preferably implemented in a microstrip metallization network, coupled to an active antenna patch element to feed the active antenna patch element to emit a field to parasitically stimulate a parasitic antenna patch element.

Stacked patch antenna with distributed reactive network proximity feed

A mobile communication handset includes at least one passive antenna element and an active antenna element adjacent to the passive antenna elements protruding from a housing. The active element is coupled to electronic radio communication circuits and the passive antenna elements are coupled to circuit elements that affect the directivity of communication signals coupled to the antenna elements.

An antenna array that uses at least two passive antennas and one active antenna disposed above a ground plane, but electrically isolated from the ground plane, and a respective resonant strip positioned beneath each passive antenna. The passive antenna elements are positioned about the active element, and each of the at least two passive antenna elements is individually set to a reflective or a transmissive mode to change the characteristics of an input/output beam pattern of the antenna apparatus.

An antenna array includes a dielectric substrate comprising an integral center hub including a pivotal center section therein, and a pivotal wings extending radially from the integral center hub. An active antenna element is on the pivotal center section of the integral center hub, and passive antenna elements are on the pivotal wings. The active antenna element and the passive antenna elements are pivotal between a stored position and an operational position. The active antenna element and the passive antenna elements are substantially planar when in the stored position, and are substantially perpendicular to the integral center hub when in the operational position.

Folding directional antenna

An antenna includes a dielectric substrate, an ative antenna element carried by the dielectric substrate, and passive antenna elements carried by the dielectric substrate. The passive antenna elements are laterally adjacent the active antenna element. A respective impedance element is selectively connectable to each passive antenna element for antenna beam steering. Image elements are carried by the dielectric substrate, and a respective image element is connected to each impedance element and ground.
