摘要： A beam steering antenna system for external antenna configurations for fixed and mobile communication devices is described where one or multiple beam steering antennas are integrated into a single external enclosure and where multiple enclosures containing beam steering antennas are used with a single communication device. Where multiple external enclosures are used with a single communication system such as a WLAN access point the beam steering antenna system provides an electrical means of optimizing antenna system and communication link performance as compared to mechanical means such as antenna enclosure positioning or orientation. Radiation mode selection for 2.4 GHz and 5 GHz antennas integrated into an external enclosure on a WLAN access point allows for independent optimization of the antenna systems for the two frequency bands without requiring antenna movement or positioning. If the antenna enclosures are movable or capable of rotation the beam steering antennas can be optimized for enclosure orientation.

摘要： An antenna system is described where uniform radiation pattern coverage is provided in the plane of a low profile antenna element. A polarization that is orthogonal to the plane of the low profile antenna element can be achieved for the radiated field. Tuning mechanisms are described to provide a method for dynamically altering the radiation pattern and for adjusting the frequency response of the antenna during the manufacturing process as well as at field installation. The antenna system is capable of being implemented in applications such as local area network (LAN), cellular communication network, and machine to machine (M2M).

摘要： A wideband array capable of MIMO operation and possessing low Passive Intermodulation (PIM) characteristics is described for use in Distributed Antenna Systems (DAS) and other applications which require low PIM levels. The antenna can be configured to provide a narrow radiated beamwidth across multiple frequency bands and can support high power levels. A novel antenna design is implemented to populate the array configuration, wherein both fed and counterpoise elements are isolated from the ground plane to provide low PIM performance, while maintaining constant beamwidth across wide frequency ranges.

摘要： A two antenna assembly for use in MIMO systems is described where wide beamwidth performance is achieved over wide frequency ranges while maintaining high isolation and low envelope correlation between the antenna elements in a low profile, small form factor. This MIMO antenna system is optimal for use in DAS systems for in-building applications where a MIMO antenna system is required and a low profile is desirable for ceiling and wall mount applications. The antenna assembly is designed to maintain low Passive Intermodulation (PIM) characteristics across multiple cellular frequency bands. Each antenna in the pair of elements is configured to cover multiple cellular frequency bands to provide a single port per antenna for use with multiple transceivers. A single conductor radiator design for the antenna elements simplifies manufacturing of the antenna. A tuned parasitic element is positioned between the antenna elements to enhance isolation at specific portions of the frequency range.

摘要： An antenna system is integrated into a cover or accessory and adapted to couple to an antenna in a host device to improve transmission and reception of signals. The antenna system can be passive or active, with the active antenna system designed to amplify coupled signals on the integrated antenna elements in the cover or accessory. Single or multiple frequency bands can be improved with the integrated antenna system, and multiple antennas in the host device can be coupled to and improved. The antenna system can couple to the existing antennas in the host device by capacitive coupling, i.e. no physical contact required, or a connector can be designed into the cover or accessory containing the integrated antenna system that makes contact to electrical ground of the host device or power supply signals or other control signals.

摘要： A modal antenna array is described where modal antenna elements capable of generating multiple radiation modes are used to form array radiation patterns. Nulls in the array radiation pattern can be formed and positioned by proper modal antenna element mode selection, with these nulls used to provide interference suppression or mitigation. The shift in array radiation pattern maxima generated by modal element mode selection can be used to improve communication system link quality by optimizing array radiation pattern characteristics. Specifically, a ring or circular array configuration is described where a simplified common feed port can be implemented to feed multiple modal antenna elements used to form the array. A switch can be used to connect or disconnect one modal element from the array, with this feature providing additional unique array beam states. The modal array can be commanded via a look-up table or algorithm.

摘要： An antenna comprising an IMD element and one or more parasitic and active tuning elements is disclosed. The IMD element, when used in combination with the active tuning and parasitic elements, allows antenna operation at multiple resonant frequencies. In addition, the direction of antenna radiation pattern may be arbitrarily rotated in accordance with the parasitic and active tuning elements. Unique antenna architectures for beam steering in Wi-Fi band applications is further described.
