In detail, the radiator 100 is formed of a conductive material, and serves as an antenna that generates an induced current by electromagnetic waves or generates electromagnetic waves by electric current to perform physical input / output of a signal.

In addition, the radiator 100 may be formed of a metal plate having a predetermined length and width, and may form a predetermined three-dimensional pattern that is bent or curved. In addition, the three-dimensional pattern structure may have a form that is easy to receive and design multiple frequencies according to an embodiment of the present invention. In addition, the radiator 100 may be directly disposed on the substrate 200 to customize a corresponding antenna according to a band characteristic to be received without using a dielectric, and may be provided in a vertical form with a double structure of the substrate 200. The space utilization can be maximized.

Particularly, the radiator 100 may be formed by bending the radiator to be vertically coupled to the substrate 200, and the first vertical radiator 120 formed below by one or more double bends, and one end of the first vertical radiator. And a second vertical radiator 140 supported by the pillar body 130 formed in the upper part and parallel to the first vertical radiator 120, wherein the first vertical radiator 120 and the second vertical radiator 120 are formed. The radiator 140 may include one or more uneven parts 121 and 141 for adjusting reception frequency.

The bending structure of the radiator 100 formed as described above may be formed to have various electrical lengths according to the frequency to be used in the antenna.

Facilitating gain and bandwidth adjustment in receiving multiple frequencies of multiple bands according to an example.

More specifically, first, the radiator 100 is vertically connected to the signal input terminal 220 of the substrate 200, and one side of the signal feeding unit 105 and the signal feeding are connected to the first vertical radiator 120. It may include a ground feeding unit 110 is extended and bent from the other side of the portion 105 is inserted into the ground 210 of the substrate.

In addition, the first vertical radiator 120 is generally opposite to the ground feeding part 110 while maintaining a vertical state with respect to the substrate 200 from one edge 124 of the signal feeding part 105. The substrate 200 may extend in parallel with the substrate 200 in a transverse outward direction (X direction in FIG. 2).

Here, the first vertical radiator 120 extends a predetermined length from the one side 124 of the signal feeding unit 105 in the transverse outward direction (X direction), and is then bent downward to form one lower end 123. The first concave-convex portion 121 may be formed from the lower end 123 to protrude at a first interval according to double bending.

Here, the first uneven portion 121 may be parallel to the substrate 200 and protrude in the longitudinal direction of the vertical substrate 200 in the vertical direction corresponding to the direction of the first vertical radiator (Y direction in FIG. 2). have. To this end, the first vertical radiator 120 is first bent in the longitudinal inward direction (Y direction) at the lower end 123, and secondly bent in the transverse outward direction (X direction) relative to the substrate 200. Can be formed to protrude.

In addition, the first uneven portion 121 may be first bent at an end portion thereof, and may be formed to extend a predetermined length in the terminal outward direction (the direction opposite to Y). The predetermined length may be calculated by combining the protruding second interval and the first interval of the second uneven portion 141 to be described later, the second body is bent at the extended end to form a predetermined height 130 Can be.

It may include a second fixing part 151 coupled to the vertical perpendicular to the substrate. Here, the second fixing part 151 may form an end portion of the radiator 100, and as the end direction is vertically fixed to the substrate 200, the antenna receiving direction during normal use of the mobile terminal for processing payment information. Can be specified to maximize its reception performance.

As described above, the radiator 100 having one or more uneven parts 121 and 141 formed on the first vertical radiator 120 and the second vertical radiator 140 may be formed by the first interval and the second interval of the uneven portion. According to the length adjustment of the radiator, the low frequency reception band of the multi-frequency reception band of the radiator is determined to facilitate the antenna design and adjustment.

For example, as shown in FIG. 3, referring to the plan view, the first interval formed by the uneven parts 121 and 141 may be A, the second interval may be B, and the first vertical radiator 120. The length of the radiator which is bent from the end and extends to the pillar body 130 may also be formed as A + B. According to the formation of the unevenness, the overall length of the radiator 100 may be determined by a coupling operation such as a base length + 2A + 2B, and the reception band corresponding to the required frequency band may be precisely adjusted even if only the protruding length is adjusted.

For example, the multi-frequency may include at least two frequencies (LTE band 5_830 MHz, LTE band 3_1, 7 GHz), and may be divided into a low frequency band and a high frequency band.

In addition, when the frequency to be used in the antenna is λ, the radiator 100 is formed to have an electrical length of λ / 4, so that the reception band corresponding to the low frequency is first designed as 800MHz according to the base length of the antenna can do.

When 1.7 GHz, which is a high frequency reception band of the radiator, is determined according to the length of the ground feeding part, by adjusting the first interval and the second interval for matching and multiplying the low frequency band and the two high frequency bands, Antenna designs are possible that can maximize frequency gain and bandwidth performance very easily.
