Mobile radio aerials for operation in several frequency bands, with several dipole radiator, in front of reflector, radiating in two different frequency bands, with specified spacing of radiator structure, radiator elements, etc

In front of reflector (1) are located several dipole radiators (2,3) with radiator elements or structures (102,103). At least one dipole radiator (3) is for lower frequency band and at least one radiator (2) radiates in higher frequency band. Spacing of radiator structure, radiator elements, or thei...

Zusammenfassung:In front of reflector (1) are located several dipole radiators (2,3) with radiator elements or structures (102,103). At least one dipole radiator (3) is for lower frequency band and at least one radiator (2) radiates in higher frequency band. Spacing of radiator structure, radiator elements, or their top side (102) of higher frequency radiator to reflector plane (E) of 75 to 150 per cent of specified elements. Spacing is also 0.4 to 2 lambda with respect to mean frequency of higher frequency radiator.
