A loop antenna is provided, which includes a first loop section, a second loop section and a third loop section. The first loop section surrounds and defines an empty area. The second loop section surrounds and connects the first loop section, and an annular groove is formed between the first loop section and the second loop section. The third loop section surrounds and connects the second loop section. The width of a gap between the third loop section and the second loop section is smaller than the width of the annular groove.
