ABSTRACT:
A RF antenna system mounted on, for example, a dielectric carrier plate is accommodated as a homing head in the front under a radome in a missile provided for locating radar systems or the like, in addition to other, further sensors potentially present in free spaces. The RF antenna system is composed of a three's or four's group of logarithmic-periodic crossed dipole antennas whose long axes proceed with optimized dimension obliquely relative to one another and that are interconnected with a monopulse feed network for taking aggregate and difference diagrams in azimuth and elevation. The antenna system for long-range missiles enables a monopulse position fixing in azimuthal or, respectively, elevational direction in an extremely broad frequency range.
