External mounting type microchip dual band antenna assembly

摘要

Disclosed is an external mounting type microchip dual band antenna assembly including a microchip dual band antenna connected to a printed circuit board which is disposed in a case of a portable terminal. The microchip dual band antenna comprises upper and lower patch elements respectively surrounding lengthwise upper and lower ends of a dielectric body having a shape of a quadrangular prism; a first radiation patch placed on a front surface of the dielectric body to extend zigzag from the upper patch element toward the lower patch element; a second radiation patch placed on a rear surface of the dielectric body to extend zigzag from the upper patch element toward the lower patch element in a manner such that zigzag configurations of the first and second radiation patches are staggered with each other; and a feeder channel defined on a side surface of the dielectric body adjacent to the lower patch element and plated in such a way as to connect the first and second radiation patches with each other.
