Abstract

This paper describes the development of a dualband slotted waveguide antenna for communication, navigation and surveillance radar applications. Two different slot sizes on opposite faces are designed for enabling antenna operation over two different frequency bands. In this way, it becomes possible to perform diverse sorts of tracking using a unique structure. Numerical results, obtained using ANSYS HFSS, demonstrate the proposed antenna provides two bandwidths of approximately 15% and 6.5% for S-band and C-band, respectively. The antenna gain varies from 12.7dBi at 2.2 GHz to 16.37dBi at 4.6GHz.
