Abstract :
A wideband balanced antenna for mobile handsets, covering three bands (GSM 1800, GSM 1900 and UMTS), is investigated. The antenna is a slot planar dipole with its arms folded and fed by a balanced voltage source. A wide bandwidth planar balun was adopted and modified to feed the antenna from an unbalanced source. For validation, a prototype of the antenna was fabricated and tested. The calculated and measured results in terms of return loss show good agreement and the results also show good wideband characteristics.
