Abstract

This paper presents the structure of a compound dipole with H-plane parasitic posts in an array and describes its radiation characteristics. The simulation result indicates that this dipole is not only useful for eliminating scanning blindness to achieve a wide angle-scanning, but also for improving the reflection coefficient for wide-band matching. By use of the dipole in a 7×7 array plane and an 8×10 active phased array, very good wide-band consistencies are shown experimentally
