Abstract :
A novel compact size dual-band dual-polarized antenna array for MIMO WLAN is reported. The array element comprises a periodic antenna with bowtie dipoles and a printed dipole antenna with a reflector and a director. The presented design is characterized by dual-band operation, good front-to-back ratios, average gains of 4 and 5 dBi over the 2.4 and 5.2 GHz bands respectively. A prototype 12-element array exhibits dual broad bandwidth and low mutual coupling among 2.25GHz-2.6GHz and 4.95GHz-6GHz. The measured results indicate the array is suitable for 802.11a/b/g/n systems employing MIMO and beam selection techniques.
