Abstract
The present invention discloses a low-profile broadband high-gain filtering antenna. The antenna comprises a radiator, an upper-layer dielectric substrate, a lower-layer dielectric substrate, a microstrip feed-line having open stubs, a ground plane having a plurality of spaced slots, and a metallized via. The radiator generates resonances, provides a broadband and high-gain radiation passband, and meanwhile, adjusting the dimensions of the radiator can adjust the roll-off rate at the upper edge of the passband. The open stub generates a radiation null, and suppresses a resonance in upper band of the antenna. The spaced slot suppresses a resonance in lower band of the antenna. The metallized via connects the microstrip feed-line and the ground plane, generates a radiation null, and improves the roll-off rate at the lower edge of the passband.
