Embodiments are provided for an agile antenna that beamsteers radio frequency (RF) signals by selectively activating/de-activating tunable elements on radial-waveguides using direct current (DC) switches. The antenna comprises two parallel radial waveguide structures, each comprising a first radial plate, a second radial plate in parallel with the first radial plate, and conductive elements positioned vertically and distributed radially between the two plates. The radial waveguide structure further includes a plurality of quarter RF chokes which are connected to the conductive elements via respective micro-strips and tunable elements. The two parallel radial plates are separated by a height determined according to a desired transmission frequency range for RF signals, a length of the micro-strips, a diameter of the conductive elements, and a clearance space around each one of the conductive elements.

Embodiments are provided for an agile antenna that beamsteers radio frequency (RF) signals by selectively activating/de-activating tunable elements on radial-waveguides using direct current (DC) switches. The agile antenna device comprises a first radial waveguide structure encased in a first frame, a first line feed connected to the first waveguide structure, a second encased radial waveguide structure similar and coupled to the first waveguide structure. The two waveguide structures include the tunable elements controlled by the DC switches. A second line feed is connected to the second waveguide structure. The two line feeds provide the RF signal to the antenna. The antenna device also includes a plurality of radiating elements positioned between the first radial waveguide structure and the second radial waveguide structure, and distributed radially around a circumference of the first radial waveguide structure and a circumference of the second radial waveguide structure.

A telephone set includes a cradle for receiving a selected electronic device, such as a Personal Digital Assistant (PDA). The cradle comprises a cradle base and a cradle cover coupled to the cradle base. The cradle cover includes a support for selectively securing the selected electronic device thereto. Means for coupling the cradle to the telephone set, which preferably comprises a snap device, is provided. A connector is coupled to the cradle in order to enable communication between the selected electronic device and the telephone set. The cradle can be selectively removed from the telephone set by decoupling the cradle base from the telephone set.
