Abstract
To provide an antenna system, an antenna device, and an antenna structure that are not affected by interference from frequency bands surrounding a wireless reader device.SOLUTION: In an antenna system, an antenna structure 1 includes a ring section 11, a band adjustment section 12 surrounded by the ring section, and a frequency adjustment section 13. The ring section has a first end 111 and a second end 112 respectively connected to a periphery 113 and both ends of the periphery and spaced apart from each other. The band adjustment section is connected to the first end and the periphery in the vicinity thereof, and has a first layout length L1 along a first direction D1. The frequency adjustment section is connected to the band adjustment section, and has a second layout length L2 in the first direction that is greater than the first layout length. The antenna structure 1 constructs a three-dimensional detection space through communication elements, and acquires a signal from at least one detector disposed therein.SELECTED DRAWING: Figure 3
