Reconfigurable antenna for concurrent operation over cellular and connectivity bands.

Two frequency-reconfigurable antennas have been designed and combined in a space with limited volume, i.e. 40 ×20 ×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. [ABSTRACT FROM AUTHOR]
