Abstract
The reconfigurable multiband antenna includes the main antenna element connected to a feeding point to receive and transmit a radio signal, the at least one parasitic antenna element being placed on the side of the main antenna element. The at least one parasitic antenna is connected to the main antenna element or they are connected to each other by at least one RF switch. By changing the ON-OFF combination of the RF switches, the connection between the main antenna element and the parasitic antenna element is changed, thereby changing the resonance frequencies of the entire antenna. By this technique, the entire antenna functions as a reconfigurable multiband antenna.
