Application58 Radiation Pattern of Yagi Antenna

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.
