Abstract
A method and device are for calibrating an antenna. At least one switch is spanning sections of a radiating antenna element. A controller is designed to selectively close the switch to be conductive, thus effectively short-circuiting the actual section of the antenna element. The method includes: installing the antenna for field use at least for transmission or reception of signals; then measuring the reflected power from the antenna at least for a number of frequencies or frequency ranges at more than one setting of the switch; and storing the settings that gives a desirable result of reflected power at an actual frequency or frequency range.
