Wireless Communications
The desired azimuthal antenna pattern is either (i) omnidirectional—i.e., uniform
in [0, 2π)—or (ii) uniform within a sector, and zero outside. The angular range of a
sector is usually 60° or 120°. For omnidirectional antennas, which are mostly ...

Radar Principles for the NonSpecialist, 3rd Edition
By computing the ratio of an integration from 0 to π (the first null) and from 0 to ∞,
we can find just under 90% of the antenna gain is contained within the null-to-null
beamwidth. We have already noted that the nulls in the antenna pattern are at ...

Antenna and Wave Propagation
Radiation or antenna pattern describes the relative strength of the radiated field
at various orientations from the antenna at a constant distance. The radiation
pattern is a 'reception pattern' as well, since it also describes the receiving
properties ...
