US 8,432,327 B2 · Dual-band dipole antenna

Abstract

A dual-band dipole antenna (100) includes a ground radiating portion (2), a signal radiating portion (3) and a feed wire (1). The feed wire (1) has a ground portion (12) connected to the ground radiating portion (2), and a core conduct (11) connected to the signal radiating portion (3). The signal radiating portion (3) has a first branch (31), a second branch (32) having a same length and a same width as the first branch (31), and a middle portion (33) connecting the first branch (31) and the second branch (32) at connecting points. Each of the first branch (31) and the second branch (32) has a first radiating length (D1) extending from the connecting point and a second radiating length (D2) extending from the connecting point.
