Scope

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) Multimedia Wireless Systems (MWS), 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 [5], specifies the requirements for MWS (Multimedia
Wireless Systems) [3] operating in the frequency range 40,5 GHz to 43,5 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 [2].
