A Direction-Finding Antenna Inserted into the Surface of Cylindrical Conductor Body
Abstract
In this letter, a direction-finding antenna inserted into the surface of a cylindrical conductor body, with the conductor material in front of the antenna, is presented. To minimize a gain reduction in the axis direction of the cylindrical conductor, an aperture of an open-ended waveguide antenna is modified, and the conductor body is deformed. The antenna is operated at the X-band, and its direction-finding performance using an amplitude comparison method is analyzed. To verify the validation of the performance of the antenna, the analyzed results are compared to the measurement results.
