Abstract

A small PIFA using multi-band, wide-band, high-isolation MIMO techniques, covering GSM900/DCS/PCS/UMTS/WLAN operational bands, has been demonstrated using both simulations and measurements. In order to achieve the wide bandwidth required for DCS/PCS/UMTS services, a resonator and a meander shorting line were adopted. In addition, a modified neutralization link was incorporated to obtain the high isolation characteristic necessary for a MIMO WLAN service. Simulations and measurements demonstrated very similar results for S-parameters, ECC, and radiation patterns. In addition, Good diversity characteristics for the WLNA band are also achieved. Therefore, the proposed antenna combining a multi-band antenna with MIMO antennas will be useful for future mobile handset applications.
