This letter presents a reconfigurable antenna with a microstrip patch that uses PIN-diode connections on slits to achieve frequency diversity. By switching the diodes on or off, a surface current path on the antenna is changed, which effectively results in shifting the operating frequency. Thus the antenna can select both WiBro and DMB bands.
