Abstract
There is disclosed a method which is capable of calibrating or tuning the characteristics of individual antenna elements constituting an array antenna. The performance of the individual antenna elements can be improved by calibrating or tuning the characteristics of the individual antenna elements, and thus an array antenna can be installed even in a narrow space and can receive GPS signals.
Claims6
A method of tuning an array antenna, the method comprising:
- measuring characteristics of individual antenna elements included in an array antenna, and generating measured values;
- selecting a superstrate corresponding to each of the antenna elements from among a plurality of superstrates based on generated measured values of the antenna element;
- and
- joining the selected superstrate to the corresponding antenna element
- wherein each of the antenna elements is a double ring antenna including an inner ring and an outer ring which are concentric to each other;
- and
- wherein each of the superstrates has a shape including a first cylinder configured to be inserted into a space inside the inner ring and a second cylinder configured to be located on the first cylinder.
