Design of Frequency Reconfigurable Antenna For Multi Standard Mobile Communication
نویسنده
چکیده
The develpoment of smart antennas for mobile phones has recently recevied much interest due to compact size of multimode phones and requirements to keep the amount of RF power absorbed by a user below a certain level. In this paper a new Yagi Uda shaped frequency reconfigurable antenna for multimode mobile applications has been presented. The proposed fabricated antenna have return loss better than -10dB, VSWR below 2, radaiation efficiency greater than 60% and SAR below 2W/kg for all the frequency bands. The proposed antenna structure is compact in size, offer high isolation between eight transmitting bands. PIN diodes are used to switch the frequecny bands between WCDMA, FDMA, PDC, GPS (1.56-1.585 GHz), GSM1800 (1710-1880MHz), PCS1900 (1859-1990MHz), UMTS (1900-2170MHz), DCS1800, WLAN, Bluetooth, Wi-Fi etc.
