Abstract

A method and system for point-to-point wireless communications utilizing leaky wave antennas is provided. In this regard, a first device may transmit a RF signal via a leaky wave antenna, and may determine an angle between the leaky wave antenna of the first device and a leaky wave antenna of a second device by adjusting a frequency of the RF signal until a response is received from the second device. The first device may be configured based on the determined angle. A wireless connection may be established between the leaky wave antenna of the first device and the leaky wave antenna of the second device based on the configuration. The first device may generate a notification when the angle is beyond a threshold. The wireless connection may adhere to wireless USB protocols and/or Bluetooth protocols, for example. The second device may generate the response after receiving sufficient energy from the RF signal.
