In this paper, we proposed a broadband dual-band base station antenna with L-T probes fed structure for mobile communication. The two-layered patch antenna and antenna array for the CDMA, GSM, PCS and IMT-2000 (824-960 MHZ, 1710-2170 MHz) dual band are studied. In an attempt to enhance the impedance bandwidth, the rectangle patch antenna is fed by L and T probes, and it has been experimentally studied. By using foam layers of thickness 0.075 λ1 and 0.075 λ2 (λ1 and λ2 represent the free space wavelength at the center frequency of the lower and upper band respectively) to support the patches that are responsible for the lower and upper band, an impedance bandwidth (S11<-10 dB ) of 15.2% and 23.7% have been obtained respectively. The far field patterns are stable across the passband. The antenna array of two (three) units is tested and the results are satisfied. (3 pages)
