13. 9 Alternative three-dimensional electric ﬁeld radiation pattern of a half-wave dipole antenna. 10 Alternative three-dimensional electric ﬁeld radiation pattern of a hypothetical pyramidal horn antenna. 9. Whether a polar or a rectangular plot of the radiation pattern is used, is mainly a matter of taste. The author’s taste is for rectangular patterns, especially for observing details, and for power patterns over ﬁeld patterns. 4 Power Patterns The radiation patterns shown thus far have been so-called ﬁeld patterns.

10 Alternative three-dimensional electric ﬁeld radiation pattern of a hypothetical pyramidal horn antenna. 9. Whether a polar or a rectangular plot of the radiation pattern is used, is mainly a matter of taste. The author’s taste is for rectangular patterns, especially for observing details, and for power patterns over ﬁeld patterns. 4 Power Patterns The radiation patterns shown thus far have been so-called ﬁeld patterns. In general, we are not directly interested in the angular electric ﬁeld amplitude distribution, but more in the angular power distribution.

The accepted power) is distributed in space. The gain, G, is the maximum of the gain function, G = max[G(ϑ, ϕ)]. 12) The quotient of gain and directivity equals the quotient of total radiated power and total accepted power and is called the radiation efﬁciency, η [3]. η= G Pt = . 13) The efﬁciency is smaller than one due to ohmic and/or dielectric losses in the antenna. 6 Antenna Beamwidth In comparing antennas we may use the gain we just discussed. But this is a number that only tells us about the maximum radiation.
