Fixed Radio Systems - Point-to-Multipoint Antennas - Antennas for multipoint fixed radio systems in the 11 GHz to 60 GHz band - Part 4: 30 GHz to 40,5 GHz
The present document specifies the essential electrical requirements for linear polarization, fixed beam antennas to be
utilized with new MultiPoint (P-MP and MP-MP) systems EN 301 997-1 [1], including Central Station, Repeater and
Terminal Station applications, operating in frequency bands from 11 GHz to 60 GHz. These systems use various
multiple access schemes. Antennas may be aligned manually, by electromechanical or by switching between a set of
antennas. Electronically steered antenna arrays, and circularly polarized antennas are not considered in the present
document.
The present document, taken together with EN 301 215-1 [4], specifies the requirements for multipoint systems
operating in the frequency range 30 GHz to 40,5 GHz.
A Regulatory Authority may impose tighter requirements than the minimum values given in the present
document, in order to maximize the use of scarce spectrum resources.
For some high gain multipoint requirements, antennas may be used having performance as per the appropriate
point-to-point antenna standard. For these antennas, minimum requirements are given in EN 300 833 [2].
