Broadband antenna

摘要

A broadband antenna includes a dielectric substrate (110), a radiation conductor (120) and a feeding gap (130). The radiation conductor (120) is disposed on the dielectric substrate and has a first side (121) and a second side (122). The first side (121) is adjacent to the second side (122), and the first side (121) is longer than the second side (122). The second side (122) has a first feeding point (125) and a second feeding point (126). The feeding gap (130) has a first end (131) located at the first side (121) and a second end (132) located at the second side (122). The feeding gap (130) divides the radiation conductor (120) into a first sub-radiation conductor (123) and a second sub-radiation conductor (124). The first feeding point (125) is located on the first sub-radiation conductor (123) and the second feeding point (126) is located on the second sub-radiation conductor (124).
