Antennas for millimeter wave distributed antenna systems or indoor radio systems are disclosed. According to one aspect, an antenna system is configured to provide a static composite radiation pattern, the static composite radiation pattern having a static broadside radiation pattern and a static off-center-axis radiation pattern. The antenna system includes a first antenna element configured to provide the static broadside radiation pattern, the static broadside pattern encompassing a broadside direction. The antenna system also includes a plurality of additional antenna elements configured in proximity to the first antenna element to provide a static off-broadside radiation pattern, the combination of the static broadside radiation pattern and the static off-broadside radiation pattern providing the static composite radiation pattern. A beamformer is configured to feed the first antenna element and the plurality of additional antenna elements to produce the static off-broadside radiation pattern.

Antenna solution for mm-Wave systems

An integrated Smart LED Light/3GPP radio fixture, comprising: a Smart LED light fixture; and a 3GPP radio unit configured to transmit and receive radio signals within a coverage area that corresponds with an illumination coverage area of the Smart LED light fixture.

5G integrated smart LED lighting system

A method, system and apparatus for an optimized radiation pattern for an indoor ceiling and/or wall mounted radio unit for distributed antenna systems/radio dot systems (DAS/RDS) are disclosed. According to one aspect, a method includes obtaining beam forming weights for generating a shaped radiation pattern that provides a same effective isotropic power radiated (EIPR) at multiple locations inside a target cell, and applying the obtained beam forming weights to signals directed to an array of antenna elements of the radio interface to generate the shaped radiation pattern.
