Electromagnetic analysis is applied to the Yagi antenna.
Yagi antenna consists of one driven element, one reflector element, and six waveguide elements as in Fig. 1.
The S-parameter of the analysis result is shown in Fig. 2.
The 2D directivity and the 3D directivity are shown in Fig. 3 and 4 respectively.
Sharp directivity is generated by using a reflector element and waveguide elements.
