Abstract
Methods and systems for dynamic control of output power of a leaky wave antenna (LWA) are disclosed and may include configuring one or more LWAs in a wireless device to transmit RF signals at a desired frequency. The LWAs may be integrated in support structures, including an integrated circuit, an integrated circuit package, and/or a printed circuit board. Impedances that are coupled to the LWAs and to a power amplifier enabled to amplify the RF signals may be dynamically configured. A resonant frequency of the LWAs may be tuned, which may be configured to transmit the RF signals at a desired angle from a surface of the support structure. The LWAs may include microstrip or coplanar waveguides where a cavity height of the LWAs may be configured by controlling spacing between conductive lines in the waveguides. The impedances may include capacitor arrays and/or inductors in the support structures.
