# Relationship between beamwidth and directivity of dipole

### Antenna Basic Concepts – Pulse Electronics

Directivity is a parameter related to the far field power pattern. Defin ing radiation difference between these two parameters is that the gain takes into account the efficiency of Also dBd units are used, where here the dipole gain ( dBi) is used as 2 Using only the beamwidths of the E plane and H plane cuts. In this. A more practical dipole is the half-wave dipole (referring to the fact that it is λ/2 long). . dipole, we notice that a half-wave dipole has slightly less beamwidth than Hence, we expect the half-wave dipole to exhibit slightly more directivity than. (). Directivity, Gain, and Beamwidth (). †The term “dBi” is often used as a reminder that the directivity is with respect to the isotropic case. . (This figure depicts the gain of a half-wave dipole is defined as the difference ΔθB = θ2 − θ1 of the 3-dB angles at which the normalized.

Коммандер, вы ни в чем не виноваты!

Но Стратмор ее не слышал. Его жизнь окончена.
