A multi-mode antenna system include at least a first modal antenna and a second modal antenna. The first modal antenna is disposed on a ground plane of a circuit board and configurable in a plurality of different modes. The first modal antenna can include a driven element, at least one parasitic element and an active element configured to adjust a reactance of the at least one parasitic element. The multi-mode antenna system further includes a second modal antenna disposed on the ground plane and configurable in a plurality of different modes. The second modal antenna can include a driven element, at least one parasitic element, and an active element configured to adjust a reactance of the at least one parasitic element. The parasitic element of the second modal antenna is positioned such that adjusting the reactance of the parasitic element affects the radiation pattern associated with the first modal antenna.

Incoming calls are received from audio capable devices. A call processing server receives an incoming call from an audio-capable device to a destination number, and detects availability for an ancillary source device linked to the audio-capable device. A set of data is provided to the ancillary source device. The set of data specifies graphical menu options for functions supported by the call processing server. The ancillary source device provides an indication of a selection of one of the graphical menu options. In response to the indication, a call transfer for the incoming call is implemented.

The present invention generally relates to an electromagnetic field vector sensing receive antenna array system for installation and deployment on a structure. A multipolarized array of collocated antenna elements is used to provide calibrated amplitude and phase radiation patterns with monopole, dipole, and loop modes generated from crossed loops connected to a be informer. The invention has applications for installation and deployment on a tower, balloon, or satellite for radio frequency sensing and location of low-frequency galactic emissions. The novel receive antenna array system comprises a multipolarized vector sensor antenna array. The disclosed direction-finding vector sensor can be installed and deployed on a structure and can detect and locate radio frequency emissions from galactic sources. The key system components of the receive antenna array system consist of deployable antennas, receivers, signal processing computer, and communications link.
