| Predmet normy: | This European Standard (EN) defines the characteristics and general requirements for antennas used in fixed point-to-point radio systems (P-P FRS) operating typically in frequency bands above 1 GHz. It establishes the system-independent parameters and performance categories applicable to all types of P-P antennas, regardless of frequency band or system capacity. Specifically, it: defines antenna radiation pattern envelopes, gain, cross-polar discrimination, and mechanical characteristics; provides a classification scheme for antennas according to their directivity and interference-mitigation performance; specifies test methods and measurement accuracy for verification; and describes the relationship between antenna performance and spectrum efficiency, supporting coordination and licensing processes. ... |
