ANTENNA FOR MULTI-FREQUENCY OPERATION
2002An improved antenna comprising at least two individual radiators (1, 2) can be operated in at least two frequency bands (f1, f2, ..., fn). The antenna is improved by the following measures: each output of the individual radiators (1), which can be operated in at least two frequency bands (f1, f2, ..., fn), or the output of a group of corresponding ...
