- the solid line shows the time when the case is opened, and the double dotted line shows the case where the case is closed so as not to change the twist angle.
- Patent Document 2 JP 2002-33804 A (Patent Document 2)
- each casing 2 0 2 and 2 is closed if it is closed.
- the currents flowing to 0 3 are in phase (arrows G and H are in the same direction). That is, it flows from the end where the antenna 2 0 1 is provided to the opposite end.
- the case current (arrow I) flowing to the first case 202 is the same as the case current (arrow G) in the closed state.
- the direction of the case current (arrow J) flowing to the second case 2 0 3 differs from the direction of the case current (arrow H) flowing to the first case member 2 0 2 (opposite phase become) . For this reason, there is a risk that the radiation efficiency may be reduced if the closed state is opened. Therefore, there is a problem that the radiation efficiency may be reduced depending on the connection method of the housing and the antenna.

- FIGS. 6A and 6B show the closed state of the case (first and third open states) and FIG.
- the first housing member 101a is connected by capacitive coupling (floating capacitance) to the second housing member 101b having the second antenna 103b, It is insulated to the
- the first housing member 1 0 1 a acts as a reflector when the two housing members 1 0 1 a and 1 0 1 b are in the closed state, and in the first open state, the waveguide is provided. Work To use.
- the closed state shown in FIG. 16 (a) the directions of the high frequency current (case current) flowing in the first and second case members 101a and 101b are as shown by arrows A and B, respectively, and The second housing member 101 b side becomes larger.
- the magnitude of the high frequency current flowing in the first housing member 101a with respect to the high frequency current flowing in the second housing member 101b is opposite.
- the direction in which the high frequency current flows is reversed with respect to arrow B.
- the direction of the high frequency current flowing to the side of the second housing member 10 1 a indicated by the arrow D is the same as that of the arrow A. Therefore, in the first open state, the electromagnetic waves are emitted also from the first housing member 10 1 a side.
- the high frequency current (arrow E) flowing to the second housing member 101b has a high circumference flowing to the second housing member 101 b in the closed state. It is the same as the wave current (arrow A).
- the first housing member 101 a since the first housing member 101 a intersects with the second housing member 101 b, the first housing member 101 a is not guided. It does not act organically, it is similar to the closed state. Therefore, the direction of the high frequency current (arrow F) flowing in the first housing member 101 a is substantially orthogonal to the high frequency current (arrow E) flowing in the second housing member 1 O l b.
- the case current (arrow F) on the side of the first case member 101 a does not cancel out the case current (arrow E) on the side of the second case member 101 b. Therefore, the electromagnetic wave is radiated from the side of the first housing member 101 a in addition to the side of the second housing member 101 b without causing a decrease in the gain of the second antenna 103 b.
- the present invention is not necessarily limited thereto.
- the terminal end of the second antenna (opposite to the feeding part) It may be configured to extend in the direction away from 102, that is, in the direction from the hinge portion 102 toward the battery side (the end side of the second housing member 101 b).
- the first housing member functions as the radiator described above.
- the form of the antenna may be plate-like or rod-like because it can radiate magnetic waves.
- FIG. 18 (a) and (b) are the VSWR characteristics and impedance characteristics in the closed state of the casing in the tightly coupled state, and (c) and (d) are the first of the casing in the closely coupled state.
- the simulation results of V SWR characteristics and impedance characteristics in the open state are shown.
- the VS WR characteristics (a) and (c) of the two states in this closely coupled state are compared, when the case 101 is changed from the closed state to the first open state, the VSWR changes in the vicinity of the 2 GHz band It is clear that there is almost no deterioration, but deterioration on the low band side (near 0.9 GHz). The reason is that the higher the frequency, the larger the current flowing to the antenna and the smaller the housing current, and the lower the frequency the smaller the current flowing to the antenna and the larger the housing current. The influence of the negative phase current flowing to the member 101 a greatly contributes to the lower frequency. From this result, it is understood that the first housing member 1 O 1 a and the second housing member 1 0 1 b should preferably be loosely coupled particularly when using a multi-frequency antenna.
- the radiation characteristic of the low frequency side resonance frequency band is degraded. Therefore, in the case of using a multi-frequency antenna, it is better to loosely couple the two housing members 10 l a and 10 l b to obtain a better antenna gain.
- the user in the first open state, holds the second housing member 101b in hand, places the receiver 106 of the first housing member 101a on the ear, and talks When making a videophone call, use the first housing member 101a away from the head.
- the second housing member 101 b in the second open state. Therefore, in the first open state, since the first casing member 101 a that emits the electromagnetic wave is not covered by the hand holding it, reduction of the antenna gain can be avoided, and good transmission and reception can be performed.
- the third open state is the same as the closed state, but the side face side provided with the second antenna 103 b of the second housing member 10 lb and the first housing member 101 a Because it is not covered, it is possible to reduce the loss of gain from being held by hand.
- the housing 101 changes from the closed state to the open state.
- the curvature of the first winding portion 1 3 9 b changes and the distance between the two becomes narrow, and the capacitance between the flexible substrate 1 3 9 and the feeding portion 1 0 3 h of the second antenna 1 0 3 b Induce a bond.
- the frequency characteristics on the low band side become narrow band radiation characteristics.
- the flexible substrate 1 3 9 and the feeding portion 1 0 3 h are separated from each other, and the end portion where the antenna current is substantially zero (second element portion 1 0 3 d End) and the first wound portion 1 3 9 b are in close proximity to each other.
- the first winding portion 1 3 9 b and the second antenna 1 0 1 b are not capacitively coupled even when the housing 101 is operated to open and close, band narrowing is prevented, and further, It is possible to prevent the reverse phase of the casing current on the side of the casing member 101 a. That is, it is possible to control the case current so that the case current on the first case member 101 a side is in the same phase as the second case member 101 b side. . Therefore, regardless of the open / close state of the housing 101, reduction of the gain of the second antenna 103 can be avoided.
- FIG. 19 shows the closed state of the housing, (b) shows the third open state, and (c) shows the first open state.
- the flexible substrate 1 3 9 is disposed substantially linearly downward from the first winding portion 1 3 9 b.
- the third (or second) open state in which the housing 101 shown in FIG.
- the distance between the flexible substrate 1 3 9 and the second antenna 1 0 3 b is narrowed, which results in a decrease in gain of the second antenna 1 0 3 b.
- the openable communication terminal having the flexible substrate passed through the hinge portion even when the flexible conductor and the antenna are disposed close to each other, Since the flexible substrate and the feed portion of the antenna are separated, it is possible to avoid the decrease in antenna gain due to the flexible conductor. This makes it possible to suppress the degradation of the antenna gain in either the open or closed state.
- an open-close communication terminal having a flexible substrate it is possible to provide a communication terminal capable of extending the life of the flexible substrate and further incorporating an antenna.
