A Comparative Performance Analysis of Two Printed Circular Arrays for Power-Based Vehicle Localization Applications

A Comparative Performance Analysis of Two Printed Circular Arrays for Power-Based Vehicle Localization Applications

A comparative study of the performance characteristics of a printed 8-element V-shaped circular antenna array and an 8-element Yagi circular array operating at 2.45 GHz for vehicular direction finding applications is presented. Two operating modes are investigated; switched and phased modes. The arr...
