Abstract
This paper proposes the conflguration of a dual- polarized wide-band patch antenna system suitable for indoor mobile communication applications. This conflguration consists of two patch antennas, which have difierent feed structures from classical patch antenna conflguration. These antennas, which are separated by a thin absorber to have a good isolation, are fed independently to obtain dual polarization. The antenna structure is designed, simulated, manufactured and measured. The operation bandwidth spans 1900{ 2700MHz covering Bluetooth, Wireless Local Area Networks (WLAN) and Universal Mobile Telecommunications System (UMTS) bands. The simulations show good agreement with the measurement results that the antennas have return losses higher than 15dB, and the coupling between two antennas is below i20dB within the operation band.
