DIPOLE ANTENNA

摘要

A dipole antenna (20, 90) includes a substrate (200), a first radiation element (20a), a second radiation element (20b) . The first radiation element disposed on the substrate includes a first bent portion (BND_1a) and a second bent portion (BND_3a). The second radiation element disposed on the substrate includes a third bent portion (BND_1b) and a fourth bent portion (BND_3b). A first feed-in point (206a) is disposed between the first bent portion and the second bent portion and a second feed-in point (206b) is disposed between the third bent portion and the fourth bent portion. The first radiation element and the second radiation element are spaced apart by a gap (D) and have reflection symmetry with respect to a symmetrical axis (axis).
