Dipole antenna

Introduction：

A tuned half-wave dipole antenna is an important antenna.The characteristics of a half-wave dipole can be calculated using Maxwell and Hertz equations.The ideal (lossless) half-wave dipole has an isotropic gain of 2.15 dBi and an impedance of 73 ohms.Therefore, dipole antennas are generally used as a reference antenna for testing.

Uses:

Dipole antennas have oscillators that are variable in length (telescopic) or have a fixed length. The most important applications are test site assessment (NSA, Standardized Site Attenuation) and ERP determination of EIRP (Effective Isotropic Radiated Power).
