For rough use in electronic proximity fuses or spacing fuses operating in the microwave range, wideband matching to the characteristic impedance of the system with small standing wave ratio is realised in simple manner by means of an aerial arrangement with two aerial units 8,9 electromagnetically coupled by dielectric 7. The one aerial unit 8 is a monopole coupled to the centre conductor 4 of an asymmetric feed. The other aerial unit 9 is a dipole which is constrainedly symmetrised through a conductive connection of its foot ends with the return conductor 5 of the feeding-in line. In a preferred embodiment (Fig. 3), the two aerial units are strip lines 13, 14 on respective facer of a dielectric substrate 15. <IMAGE> |
