Terms starting with ‘G’
- The maximum gain of a wireless antenna is simply defined as the product of the directivity by efficiency. If the efficiency is not 100 percent, the antenna gain is less than the directivity. When the reference is a lossless isotropic antenna, the…
- Gain Pattern
- Normalizing the power/field to that of a reference antenna yields a gain pattern. When the reference is an isotropic antenna, the gain is expressed in dBi. When the reference is a half-wave dipole in free space, the gain is expressed in dBd.
- Ground Plane
- There are a variety of ground planes, including drooping ground planes, and flat circular ground plane antennas. A ground plane may consist of a natural surface, such as the Earth (or ocean) (or salt marsh) or an artificial surface of opportunity…
