Localized Electric Field Generating for Rats Head Using a Patch Antenna in 26.5 GHz Band

: In this paper, two types of patch antenna that can be used for animal experiments are proposed. The proposed antenna can generate a localized electric fi eld at the head of the rat. The operating frequency of the system is 26.5 GHz. This frequency is used the fi fth generation of mobile communication (5G). The localization of the electric fi eld is evaluated by the ratio between target area fi led and whole body fi eld.
