Abstract:
1. A capacitive loop antenna, comprising: a shorting-to-ground terminal, for providing grounding; a feeding terminal, for receiving a first radio frequency feeding signal; and a first capacitive loop, comprising: wherein a first section of another end of the first radiator is capacitively coupled with the second radiator to form a first electric loop from the end of the first radiator to the end of the second radiator; wherein the signal feeding terminal is further utilized for receiving a second radio frequency feeding signal with a frequency different from a frequency of the first radio frequency feeding signal, and the capacitive loop antenna further comprises a second capacitive loop, comprising: wherein the third radiator is formed in a first layer, the first radiator and the second radiator are formed in a second layer, the fourth radiator is formed in a third layer, and the first layer, the second layer and the third layer are different layers and are in different planes.
