Wireless devices, and particularly mobile devices such as cellphones, PDAs, computers, navigation devices, etc., as well as other devices which transmit or receive data or other signals at multiple frequency bands utilize at least one antenna to transmit and receive and a plurality of different bands (e.g., GSM cellular communication band; Bluetooth short range communication band; ultrawideband (UWB) communications, etc.). These wireless devices can simultaneously transmit or receive at a plurality of different bands, or simultaneously transmit and receive at different bands. The wireless devices have the ability to use a single physical structure (e.g., an antenna for transmission and reception of many different bands. The antenna can he either actively tuned or passively tuned using one or more elements. The antenna may comprise a plurality of antenna elements or antennas, and at least one antenna may be a steerable antenna.

A communication device has a controller that selects one of at least two second antennas for concurrent transmission with a first antenna. The controller monitors concurrent communication activity of a first and a second transmitter. Based on the concurrent communication activity, the controller identifies respective transmit power limits associated with intermodulation distortion (IMD) for the first antenna transmitting at the first transmit frequency and one of the at least two second antennas transmitting at the second transmit frequency. The controller identifies available total radiated power (TRP), respectively, for each of the at least two second antennas and connects the second transmitter to one of the at least two second antennas having the highest available TRP to optimize communication performance.

Systems and methods are provided for implementing wideband radiators that conform to regular equilateral triangular lattices with little to no performance compromise for typical offset pairs of dual-polarized element arrangements. This general radiator family/group/configuration can be referred to as the Slant Tri-V (STV) element based on the basic characteristic set of this radiator group and relative differences to conventional array elements normally seen on rectangular or triangular lattice arrangements. The STV array element has wideband, dual-polarized operation and conforms to the most efficiently sampled array lattice for the lowest array element count possible for phased arrays.
