Embodiment Construction

[0031] The making and using of the presently preferred embodiments are discussed in detail below. It should be appreciated, however, that the present invention provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative of specific ways to make and use the invention, and do not limit the scope of the invention.

[0032] Disclosed herein are embodiments for flexible antennas that enable wireless transmissions such as RF or microwave signals by selectively enabling / disabling tunable elements on radial waveguides using direct current (DC) switches. beam pointing. The antenna is a dual polarized flexible antenna comprising two radial waveguides with an electronically controlled power splitter and is suitable for broadband transmission eg in the RF or microwave frequency range. As used herein, the terms RF frequency and RF signal are used to denote frequencies and signals, resp...

Abstract

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.
