Abstract
Official abstract text for this publication.
Systems, apparatuses, devices, and methods for wireless communications. An antenna in which nulls or directions of reduced performance can be selectively introduced is provided, and the performance of a communication link to a wireless communication device is monitored. By correlating the selectively reduced sensitivity of the antenna with reductions in the communication link performance, the direction of the wireless communication device may be estimated. Embodiments of the present invention may be used in numerous applications, such as cell phones, PDA's, and laptops.
First claim
Opening claim text (preview).
What is claimed is: 1. A system comprising: an antenna system having an associated radiation pattern, the antenna system including a ground plane, a first conductor element having a first length that is a quarter-wavelength of a frequency of a wireless communication link and positioned at an origin of a co-ordinate system of the antenna system, and a plurality of second conductor elements having the first length and spaced equidistantly from the origin by approximately the fi…
