7 and 8 are graphs illustrating measured radiation characteristics of an antenna device according to various embodiments of the present invention.

A graph showing the total radiation efficiency of the antenna device according to various embodiments of the present invention is shown in FIG. 7 according to frequency bands before and after the switching element S_off and S_on , And a reflection coefficient of the antenna device are shown in Fig.

As shown in FIGS. 7 and 8, in the closed state (S_on) of the switching device, the antenna device according to the various embodiments of the present invention is designed to form a resonance frequency in the 850 MHz band and the 1850 MHz band. . In an open state (S_off) of the switching device, the antenna device according to various embodiments of the present invention is set by the physical length of the first radiation portion itself or the electrical length of the first radiation portion including the concentration element I have already mentioned that it can be.

In general, when a switching element or the like is additionally arranged to secure an additional resonance frequency band in a state where the resonance frequency band is set, considerable distortion may occur in the radiation characteristic of the already set resonance frequency band. For example, a considerable loss occurs in the radiation portion due to the resistance component of the switching element. The antenna device according to various embodiments of the present invention can stably maintain the characteristics of the designed radiation part since the switching element is disposed between any one part and the other part of the radiating part. This is because the electrical length of the radiating part is adjusted by the switching element as the switching element is disposed in parallel with the radiation part, for example, a part of the radiating part, while the signal current can be distributed through a part of the radiating part arranged in parallel with the switching element Because.

When the switching element is changed from a closed state (S_on, colse state) to an open state (S_off, open state), for example, the first part P1-1 of the first radiation part 111 shown in FIG. It can be seen that when the second part P2-1 is electrically connected through the switching element S1, the resonance frequency band formed in the low frequency band shifts from 850 MHz to 700 MHz.

Generally, when the resonance frequency band is adjusted by utilizing the switching element, the resistance component of the switching element causes loss. Therefore, a considerable change may occur in the overall radiation efficiency and the profile of the reflection coefficient before and after the operation of the switching element in a general antenna apparatus.

As shown in FIGS. 7 and 8, when comparing the S_off and the S_off before and after the on / off operation of the switching device, the resonance frequency band of the antenna device according to various embodiments of the present invention changes only , The profile of the graph representing the overall radiation efficiency or reflection coefficient can be similarly maintained. Accordingly, it can be seen that the antenna device according to various embodiments of the present invention can prevent the loss due to the resistance component of the switching device while securing the resonance frequency in various frequency bands using the switching device. In addition, when the antenna device according to various embodiments of the present invention is designed as an antenna operating in a dual band, for example, a resonance frequency band of 850 MHz and 1850 MHz, it is possible to use any one of resonance frequency bands It can be seen that stable radiation characteristics can be maintained in other resonance frequency bands.
