Abstract: 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.

Abstract: 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.

Abstract: An embryo frequency leakage system for personalized wireless communication includes a base station with transceiver transmits and receives at a carrier frequency fl, an apparatus that transmits and receives at frequency fl while purposely leaks at another frequency fe; a handheld that transmits and receives at its embryo frequency fe which preferably at higher frequencies so that the handheld form factor and power consumption can be minimized. In this way, handheld only needs one low power radio therefore is green energy and less danger when pointing to human brain. The handheld will always associate with an apparatus which is deployed within personalized area and has a longer reach by using lower carrier frequencies meanwhile leaks at higher frequencies to create the second communication channel with the handheld.

Abstract: This is invention discloses a perturbation antenna system for wireless communication terminals such mobile handsets, mobile embedded laptops, mobile CPEs (Customer premises equipment), nomadic wireless CPEs, fixed wireless terminals and etc. The perturbation antenna output is analogically combined with that of the primary antenna. The combined result is to re-create the antenna pattern shape and its direction pointing in order to achieve gains by user intercept. A variable delay circuitry is equipped to the perturbation antenna therefore the user's interception can be enforced via programmable apparatus either by manually or by digital inputs. The user can tune the delay parameters meanwhile observe the antenna pattern changes and the call quality until satisfaction.
