Dynamic range detection and positioning utilizing leaky wave antennas
First Claim
1. A wireless communication device comprising:
- at least one leaky wave antenna configured to communicate signals; and
circuitry configured toset a direction in which the at least one leaky wave antenna communicates the signals by adjusting a cavity height of the at least one leaky wave antenna,receive via the at least one leaky wave antenna reflected RF signals that are reflected from an object, anddetermine a location of said object based on said reflected RF signals.

Abstract
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.
