Abstract :
This paper proposes a 2.4/5-GHz dual-band horizontally-polarized planar antenna for use in a 3-MIMO antenna configuration OFDM wireless LAN (WLAN) system. The proposed antenna provides a voltage standing wave ratio of 2 in the 2.4-2.5 and 4.9-6 GHz bands when printed on a printed circuit board for commercial PCMCIA or WLAN cards and inserted into a notebook PC. The capacities and correlation coefficients of 3times3 MIMO channels in an indoor multipath LOS/NLOS environment were measured. The results show that the proposed planar antenna is superior to the conventional monopole antenna with respect to channel capacity when polarization matching between the base station and personal station antennas is obtained.
