A tri-band shared aperture (TBSA) antenna is proposed to meet the new requirements of base station antennas for multi-band antennas fusion. The proposed TBSA (P-TBSA) antenna is composed of a lower-band (LB: 790-960 MHz) antenna, two columns of middle-band (MB: 1710-2170 MHz) sub-arrays, and a 4×8 a...
