A hybrid or combined arrangement for multi-band radiator system i.e. with dual radiation function, such as two-meter band/GPS, with noise adaptive signal amplifier arranged within the antenna housing, includes two conductive plates or foils (1,2) spaced apart from each other and coupled to a coaxial wave-guide (5), in which the inner conductor is joined to the ring-shaped plate or foil (1) and the outer conductor (5.2) of the coaxial wave-guide. The ring-shaped plate or foil (1) is coupled via a capacitive loading element (3) or a multi-pair capacitive loading element in the form of concentric functional elements or in the form of wave-guide elements with distributed parameters. The dielectric plate or foil as well as the carrier and the functional components of a large area resonator (10) are designed according to slot line- or microstrip line-technology. |
