Antenna Measurements

The development of antenna measurements techniques has evolved over time, with new measurements or methods of measurement being introduced to get around difficulties. The measuremenst are broken into:

Radiation Pattern Measurement

- Angle of radiation

- Far Field antenna ranges

- Near Field antenna ranges

Impedance Measurement

- Smith Chart

- Impedance bandwidth

Polarization

Gain and Front to Back ratios

Efficiency

Antenna Structures

- Wind loading

- Ice Loading

- Bandwidth

- Noise Figure, critically important in satellite and radio astronomoy application.

- Power Handling

Related, and often integral to antenna measurements is the use of impedance matching devices (elsewhere)
