Abstract
A telecommunications antenna comprising a plurality of unit cells each including at least one radiator which transmits RF energy within a bandwidth range which is a multiple of another radiator. The radiators are proximal to each other such that a resonant condition may be induced into the at least one radiator upon activation of the other radiator. At least one of the radiators is segmented into capacitively-connected radiator elements to suppress a resonance response therein upon activation of the other of the radiator.
Claims11
A telecommunications antenna, comprising:
- a plurality of unit cells each including a pair of radiators transmitting RF energy within a range of bandwidth, at least one of the radiators transmits RF energy within a range of bandwidth which is a multiple of another radiator such that a resonant condition may be induced into the at least one radiator upon activation of the other radiator;
- and
- wherein at least one of the radiators is segmented such that select wavelengths are filtered to avoid unwanted resonances in the at least one radiator upon activation of the other radiator,
- wherein at least one radiator includes a low-band dipole element having a dipole stem including a plurality of low-band radiator elements, each of the plurality of low-band radiator elements has a length dimension smaller than λ/7,
- wherein at least one radiator includes a high-band dipole comprising a plurality of high-band radiator elements, each of the plurality of high-band radiator elements has a length dimension smaller than λ/4,
- wherein λ is a wavelength of the RF energy transmitted by the high-band radiator elements.
