Title:
RF TAG ANTENNA AND METHOD FOR MANUFACTURING SAME, AND RF TAG
Document Type and Number:
WIPO Patent Application WO/2016/129542
Kind Code:
A1
Abstract:
[Problem] To provide an RF tag antenna in which it is possible to improve the reading performance, a method for manufacturing the RF tag antenna, and an RF tag. [Solution] An RF tag antenna 10 according to an embodiment is provided with a first insulating substrate 40 having a first main surface and a second main surface, a first waveguide element 20 provided on the first main surface, a second waveguide element 30 provided on the second main surface, a power feed unit 50 having one end electrically connected to the second waveguide element 30, and a short-circuit unit 60 having one end electrically connected to the first waveguide element 20 and the other end electrically connected to the second waveguide element 30. The first insulating substrate 40, the first waveguide element 20, the second waveguide element 30, the power feed unit 50, and the short-circuit unit 60 constitute a plate-shaped inverse F antenna for receiving radio waves transmitted from a reading device. An indictor pattern L formed by the first waveguide element 20, the short-circuit unit 60, the second waveguide element 30, and the power feed unit 50 and a capacitor 93 formed by the first waveguide element 20, the second waveguide element 30, and the first insulating substrate 40 constitute a resonance circuit which resonates in the frequency band of the radio waves.
