2 36 ELECTROMAGNETIC WAVE PROPAGATION and the efﬁciency of illumination (ηIllumination) and the loss by spillover (pSpill-over) depend on the height of the reﬂector, the relative dimensions of the antenna and reﬂector, and the form of the latter. Generally, the gain of this device is close to unity, which makes it possible for the unit to be freed from the usual branching losses by coaxial cables or waveguides on the height of the tower, or even greater than unity. Preferably the periscope must be placed in the meridian plane containing the antennas of both stations in order to not modify the plane of polarization.
8 Radiation pattern of rectangular aperture subjected to uniform illumination. 3 dB, and so on. In the same way, it is possible to reduce the side-lobe level with decreasing illumination toward the edges. 9 Radiation pattern of circular aperture subjected to uniform illumination. 10, with each features well deﬁned: 1. 10 Zones of radiation of an aperture. in a square projected aperture of size D (in meters) uniformly illuminated at a wawelength λ (in meters). Inside this zone, the energy is propagated in a tube delimited by the aperture D by presenting an equal-phase wave front and some oscillations of the amplitude versus the longitudinal axis.
15 dB. 52) In the transmission omnidirectional-type a system or one that is common to several receivers, such as broadcasting or telecommunications by satellite, it may be preferable to express the ﬁeld strength in terms of power ﬂux density or of electric ﬁeld or even of magnetic ﬁeld by using the following relations for free space: Power flux density: S(W m −2 ) = Electric field: E(V m −1 ) = Magnetic field: H (A m −1 ) = EIRP E 2(V m −1 ) 4π priso = = 4π d 2 120π λ2 30EIRP d E(V m −1 ) = 120π EIRP 480π 2 d 2 where Priso is the power, expressed in watts, collected by an isotropic radiator.
