摘要： An antenna comprising the primary and secondary radiation structures and impedance-matching circuit are disposed in a collinear configuration with single port. The impedance-matching circuit can expand the antenna bandwidth in plural frequency bands with low VSWR. The transmission line between the RF connector and radiation structures are frictional wrapped by ferrite toroid cores, which improves the antenna in term of electrical stability. This also decreases the antenna sensitivity to the ground plane.
