Antenna

An antenna for a wireless device comprising:

• a main antenna element;
• a parasitic antenna element separated from the main antenna element;
• and
• a matching element connected between the main antenna element and the parasitic antenna element.

A method of matching an antenna for a wireless device, the method comprising:

• changing parameter of a matching element on an antenna unit that includes a main antenna element and a parasitic antenna element separated from the main antenna element, the matching element having an end electrically connected to the main antenna element and another end electrically connected to the parasitic antenna element;
• measuring an antenna characteristic respectively at different parameters;
• and
• determining the best parameter for the matching element based on the measured antenna characteristic.
