Engineering Electromagnetics
The antenna radiation pattern is defined as the relative strength of the electric
field intensity, at a given distance from the antenna in the far field. The field may
be the electric field intensity, magnetic field intensity or power density, and these
...

Basic Principles of Fresnel Antenna Arrays
The Radiation Pattern of an antenna can be defined as the variation in field
intensity as a function of position or angle. Let us consider an anisotropic radiator
, which has stronger radiation in one direction than in another. The radiation
pattern ...

Microstrip Antenna Design Handbook
The effect of substrate thickness and the dielectric constant on the radiation
pattern has been discussed in [27]. The number of lobes in the radiation patterns
can be increased by increasing either h or er. These radiation patterns are
applicable ...

Satellite Communication Systems, 3rd Edition
This directional selectivity of an antenna is characterised in terms of its radiation
pattern. This pattern is a plot of relative strength of radiated field, amplitude and
phase, as a function of the angular parameters, 9 and (j), of a spherical
coordinate ...

VSATs: Very Small Aperture Terminals
2.2 Basic antenna definitions 2.2.1 Antenna radiation pattern A transmitting
antenna does not radiate uniformly in all angular directions, nor does a receiving
antenna detect energy uniformly from all directions. This directional selectivity of
an ...

Fundamentals of Geophysics
A plot of the amplitude variation with 0 is called the radiation pattern of the P-
wave amplitude, which for the single-couple model has a quadrupolar character (
Fig. 3.34a). It consists of four lobes, two corresponding to the angular variation of
...
9
Polarization, Alignment, and Orientation in Atomic ...
For symmetry reasons, the radiation pattern from an S state (L = ML = 0) that
decays to a P state (L = 1, ML = — 1,0, +1) must be isotropic as long as the
magnetic quantum number of the final state is not detected. Hence, the first
nontrivial case ...

Antenna Theory and Practice
... 10.24 to obtain the expressions for the field components of the circular aperture
or equivalent paraboloid with uniform illumination. Since the array factor given by
Eq. 11.24 is highly directional, it mainly determines the total radiation pattern.
