Abstract

Methods and systems for a touchscreen interface utilizing leaky wave antennas (LWAs) are disclosed and may include configuring one or more leaky wave antennas utilizing conductive traces in the touchscreen interface for communication of wireless RF signals. RF signals may be communicated utilizing the configured LWAs. A resonant frequency of the LWAs may be configured utilizing micro-electro-mechanical systems (MEMS) deflection. The LWAs may be configured to communicate the RF signals in a desired direction. The LWAs may comprise microstrip or coplanar waveguides, where a cavity height of the one or more leaky wave antennas is dependent on spacing between conductive lines in the waveguides. The touch control commands by the touchscreen interface may be sensed utilizing capacitance, inductance, and/or resistance measurements.
