Low-sidelobe dual-band and broadband flat endfire antenna

摘要

A low-sidelobe dual-band and broadband flat endfire antenna includes a substrate, a first radiator, a second radiator, two refraction portions, and a conductive element. The substrate has a side surface, a first surface, and a second surface. The first radiator is disposed on the first surface and has a first oblique portion, a first concave portion, and a first electrically connecting portion disposed opposite to the first concave portion. The second radiator is disposed on the second surface and has a second oblique portion, a second concave portion, and a second electrically connecting portion disposed opposite to the second concave portion. The second oblique portion is disposed opposite to the first oblique portion to form an included angle. The refraction portions are disposed on the side surface and are opposite to one another. The conductive element has a conductive body and a grounded conductor electrically connected to the first conductivity portion and the second conductivity portion, respectively.
