Abstract :
In this paper a printed dipole antenna and three slot antennas are designed to operate at 10 GHz for use in radar systems. A parametric study of each antenna and comparison between their radiation properties including return loss, bandwidth, directivity, efficiency and radiation patterns for 6-element linear array are introduced. Microstrip slot antennas show wider bandwidth, less coupling and smaller antenna size compared with the traditional printed dipole.
