A printed dipole for wide-scanning array application

The design of a printed dipole for use as a radiating element in array applications is presented. Due to careful control of mutual coupling in the E-plane, the dipole is particularly suitable for wide-scanning active antennas, such as those employed in modern multi-function radar. The printed design is suitable for monolithic integration into an active transmit/receive module. The design features a novel, compact, low-loss and wide-band balun with high immunity to breakdown resulting from high ambient field strength. The latter is particularly important in hostile EM environments such as those encountered by military applications
