Abstract :
A millimetre wave active phased array antenna has been developed that is capable of a wide scanning angle in both the E- and H-planes with small deviation in antenna gain. A dipole antenna with parasitic element has been adopted, which may have the capability of adjusting the influence of mutual coupling in the array element pattern. The design of the parasitic element is examined and the effect of its shape on pattern characteristics is confirmed by experiment. Beam scanning angles of ±57.3 degrees in the E-plane and ±68.2 degrees in the H-plane were obtained for each array antenna pattern
