Abstract
A direction-finding co-linear antenna is provided by collinearly aligning an exposed reference antenna with a primary antenna that is surrounded by a dielectric sleeve with a predetermined thickness and the reference and primary antennas are separated by a ground plane. The direction-finding co-linear antenna provides a simple, light-weight and inexpensive arrangement with fewer antennas and reduced antenna spacing that avoids unwanted detection because of a smaller electronic footprint that consists of the area of a single antenna plus a few inches of dielectric material in the sleeves rather than four widely spaced antennas positioned in an array. The direction-finding co-linear antenna apparatus also requires less electronic processing because the antenna only needs to address the RF from two antennas rather than from four or five antennas in a conventional array arrangement. The present invention also encompasses a direction-finding co-linear antenna system and a method for determining the unknown location of a signal transmission source with a co-linear direction-finding antenna.
