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...
