Abstract: A novel planar Yagi–Uda antenna is presented in this letter. The proposed antenna uses electrically small resonators as radiating elements that behave as short electric dipoles. Its radiation pattern, gain, front-to-back ratio, and efficiency are maintained close to that of a Yagi–Uda antenna of stacked half-wavelength dipoles. However, its physical dimensions are consider- ably reduced. The choice of the resonant particle and its radiation properties, along with the antenna structure, are discussed. Simulated results show a good impedance matching (–29 dB) at the working frequency of 5. 5 GHz for a 15-elements antenna, as well as a high gain (11. 5 dBi). These characteristics are experimentally validated and compared to that of other Yagi–Uda designs from the literature.
