This article presents a quasi‐Yagi antenna operating with high gain at two frequency bands. Compared with a conventional Yagi antenna, the proposed antenna is designed by integrating a pair of printed split‐ring resonators (SRRs) into the antenna layout. The SRRs introduce a new resonant frequency band and the antenna gain remains high at both the bands. The simulated and measured results show that the antenna is well matched while the antenna gain is 6 and 5.80 dBi at the GSM1800 and ISM2450 bands, respectively. The proposed antenna is compact and efficient and achieves high gain so that it could be successfully used in various wireless communication and radio frequency energy harvesting applications.
