Abstract: 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.

Abstract: Disclosed is a microchip dual band antenna mounted to a printed circuit board having a ground surface and a non-ground surface. The microchip dual band antenna comprises first and second patch elements respectively surrounding both lengthwise ends of a dielectric body having a shape of a quadrangular prism; a first radiation patch separated from the first patch element and placed on an upper surface of the dielectric body to extend zigzag toward the second patch element; a second radiation patch joined to the second patch element and placed on a lower surface of the dielectric body to extend zigzag toward the first patch element by a distance less than one half of an entire length of the dielectric body, in a manner such that zigzag configurations of the first and second radiation patches are staggered with each other; and a first feeder channel defined on a front surface and adjacent to one end of the dielectric body and plated in such a way as to connect the first and second radiation patches.
