[0064] Embodiment:

[0065] Below Figure 1 - Figure 9 A remote controller of an embodiment of the present invention is described.

[0066] The remote control of this embodiment includes a body 8, a mounting member 9, and an antenna described above. The mounting member 9 is rotated to the body 8. The antenna is provided in the mount 9.

[0067] The antenna includes substrate 1, a vibrator group, a connecting member 3, a coaxial 5, a restricted member 7, and a reflector 6.

[0068]The vibrator group includes a plurality of the first vibrator portion 2 and a plurality of, along the length direction of the substrate 1, and the first vibrator portion 2 and the second vibrator portion 4 are disposed on the substrate 1. side. The first vibrator portion 2 includes a first connected vibrator arm 21, a first high frequency vibrating arm 22, and a first low-frequency vibrating arm 23, and the first connection vibrator arm 21 extends in the width direction of the substrate 1, and the first connection vibrator arm 21 The two ends are connected to a first low frequency vibrator arm 23 and a first high-frequency vibrator arm 22, and the first low frequency vibrator arm 23 and the first high-frequency vibrator arm 22 are connected by the first connection vibrator arm 21 in the longitudinal direction of the substrate 1. Extend the setting in the same direction. The second vibrator portion 4 includes a second connection vibrator arm 41, the second high-frequency vibrator arm 42, and the second low frequency vibration damper arm 43, and the second connection vibrator arm 41 extends in the width direction of the substrate 1, and the second connection vibrator arm 41 The two ends are connected to a second low frequency vibrator arm 43 and a second high-frequency vibrator arm 42, the second low frequency vibrator arm 43, and the second high frequency vibrator arm 42 are connected by the second connection vibrator arm 41 in the longitudinal direction of the substrate 1. Extended in the same direction, the adjacent two second connection vibrator arm 41 are electrically connected by the connecting member 3; the first vibrator portion 2 and the second vibrator portion 4 are respectively disposed on both sides of the substrate 1, the first high frequency vibrator arm 22 and the first low frequency vibrator arm 23 and the second high-frequency vibrator arm 42 and the second low frequency resonator arm 43 are opposite to the opposite direction. The first connection vibrator arm 21 and the second connection vibrator arm 41 coincide with the projection of the substrate 1, the first vibrator portion 2 and the second vibrator portion 4 are symmetric with respect to the first connection vibrator arm 21. The first connection vibrator arm 21 and the first high frequency vibration arm 22 are the same, the second connection vibrator arm 41 and the second high frequency vibrator arm 42 are the same. The first connection vibrator arm 21 and the length of the first low frequency resonator arm 23 are 1/4-3 / 4 of the low frequency resonance wavelength; the length of the first connection vibrator arm 21 and the first high frequency resonator arm 22 is high frequency resonance. 1 / 4-3 / 4 of the wavelength; the second connection vibrator arm 41 and the second low frequency vibrator arm 43 are 1 / 4-3 / 4 of the low frequency resonant wavelength; the second connection vibrator arm 41 and the second high frequency The length of the vibrator arm 42 is 1 / 4-3 / 4 of the high frequency resonant wavelength.

[0069] The adjacent two first connection vibrator arm 21 are electrically connected via the connector 3. The connector 3 includes a microstrip line. The coaxial line 5 has an inner core and an outer conductor 51 that is sleeved on the inner core, and the end portion of the coaxial line 5 is inserted in the substrate 1, and the inner core and the outer conductor 51 are electrically connected to a vibrator component, respectively. The restricted portion 7 is provided on the substrate 1, and the coaxial line 5 is disposed in the limit piece 7 and spaced apart from the surface interval of the substrate 1, and the limit member 7 is used to limit the axial movement of the coaxial line 5. The two ends of the microstrip line are electrically connected to the adjacent two first connection vibrator arm 21.

[0070] Each reflector 6 is provided corresponding to a first vibrator portion 2, and the reflector 6 is used to enhance the signal of the first vibrator portion 2. The reflector 6 extends in the longitudinal direction of the substrate 1, and the length of the reflector 6 is greater than the arm of the first high frequency resonator arm 22, and is smaller than the arm of the first low frequency resonator arm 23.
