Antenna Radiation Patterns - The trace of the angular variation of the received/radiated power at a constant radius from the antenna is called the power pattern. Web the radiation pattern of an antenna is quite different in the near field, at a distance less than about a wavelength, and in the far field, with distances much greater than a wavelength. This letter investigates the impact of antenna radiation patterns in passive radio sensing applications. This can be used to extract ne features of the antenna pattern on a logarithmic scale. Due to the large variations in this value, details of pattern characteristics at lower levels may be not as apparent.

Web the radiation pattern of a transmitting antenna describes the magnitude and polarization of the field radiated by the antenna as a function of angle relative to the antenna. More simply, the radiation pattern is a trace out that corresponds to the radiation properties of the antenna in space coordinates (i.e., with respect to angle and distance). The top shows the directive pattern of a horn antenna, the bottom shows the omnidirectional pattern of a simple vertical dipole antenna. There are many reasons to use antennas but the main reason is, they provide an easy method to transmit signals wherever other techniques are not possible. The θ component of the electric field as a function of the angles θ and φ or eθ(θ,φ) Very often we will plot antenna patterns in db, which is inherently a power plot.
