Abstract
A printed circuit board antenna and a printed circuit board are disclosed. The printed circuit board antenna includes a feeding part having at least one first branch; a coupling interdigital part having at least one second branch, where a gap is formed between the first branch and the second branch; a grounding part, where a gap is formed between the grounding part and the feeding part, a gap is formed between the grounding part and the coupling interdigital part, an opening is provided on the grounding part, and a feeding point of the feeding part extends out from the opening. The embodiments of the present invention resolve a problem of relatively low efficiency when high-frequency bandwidth of an antenna is relatively wide, implementing that efficiency meets a product requirement in an entire range of bandwidth.
