RF homing head antenna system for missiles

An RF homing head antenna system that is very broadband over a plurality of octaves and that is accommodated in a front portion of a missile suitable for housing radar devices, comprising:

• a group of individual antennas attached in close spatial proximity on a dielectric carrier plate;
• a monopulse feed network for interconnecting the individual antennas of said group wherein an amplitude and phase comparison of aggregate and difference diagrams in elevation and azimuth are implemented;
• individual antennas of said group being three logarithmic-periodic crossed dipole antennas, long axes thereof proceeding inclined relative to one another such that phase centers of respectively active cross dipoles are separated by a maximum of about 0.7.multidot..lambda. in an entire range of operating frequencies.
