Method and system for dynamic range detection and positioning utilizing leaky wave antennas
View Patent ↗Methods and systems for dynamic range detection and positioning utilizing leaky wave antennas (LWAs) are disclosed and may include configuring one or more LWAs to enable communication of signals in a particular direction. RF signals that are reflected from an object may be received via the LWAs, and a location of the object may be determined based on the received reflected RF signals. The velocity of the object may be determined based on a Doppler shift associated with the received reflected RF signals. A frequency chirped signal may be transmitted by the LWAs to determine a location of the object. A resonant frequency of the LWAs may be configured utilizing micro-electro-mechanical systems (MEMS) deflection. LWAs may be situated along a plurality of axes in the wireless device. The LWAs may include microstrip or coplanar waveguides, where a cavity height is dependent on spacing between conductive lines in the waveguides.
