Abstract
A dual-polarized filtering antenna comprising a driven patch, a parasitic stacked patch and a feeding network is disclosed. Two orthogonal H-shaped feeding lines are coupled to the driven patch for realizing dual polarization. The H-shaped feeding line provides a sharp roll-off rate at the lower band-edge, whereas the stacked patch offers a radiation null at the upper stopband. As a result, a quasi-elliptic bandpass response can be achieved for both polarizations.
