Abstract
A dual band linear antenna array, having a set of radiator constructed by four elongate metal plates. The metal plates are arranged to form a rectangular array. By serially connecting to a signal feed terminal, the roots of the metal plates are connected to a copper tube via a coaxial cable external conductor (ground signal). One pair of the metal plates has the same length, which is about one quarter wavelength of the high-frequency electric wave received thereby and transmitted therefrom. The other pair of the metal plates has longer length at about one quarter wavelength of a low-frequency electric wave received thereby and transmitted therefrom. Thereby, an array of dual band antenna is obtained to achieve omni-directional reception and transmission of radiation.

A dual band linear antenna array, comprising four elongate metal plates arranged to form a rectangular array, a first opposing pair of the metal plates is longer than a second opposing pair of the metal plates, wherein the length of the first opposing pair of the metal plates is one quarter wavelength of a first electric wave, and the length of the second opposing pair of metal plates is one quarter wavelength of a second electric wave, the first electric wave has a frequency lower than that of the second electric wave.
A dual band linear antenna array, comprising three elongate metal plates arranged to form an open rectangular array, one of the metal plates is longer than the other two metal plates, wherein the length of the longer metal plate is one quarter wavelength of a first electric wave, and the length of the other two metal plates is one quarter wavelength of a second electric wave, the first electric wave has a frequency lower than that of the second electric wave.
