Two frequency-reconfigurable antennas have been designed and combined in a space with limited volume, i.e. 40 times 20 times 6 mm. Each antenna can be reconfigured to operate at different frequency bands depending on the state of an embedded switch, which is implemented using a pin diode. The first antenna can be switched between the 0.82-0.96 GHz band (GSM/CDMA) and the 1.7-2.17 GHz band (DCS/PCS/WCDMA), which are cellular bands. The second antenna can be switched between the 3.4-3.6 GHz band (mWiMax) and the 2.3-2.5 GHz, 5.15-5.35 GHz bands (WiBro/WLAN 11a/ b/g/n), which are connectivity bands. The proposed combined antenna operates over both cellular bands and connectivity bands concurrently.
