Abstract
An antenna device including a radiating conductor film having two ends adjacent to each other and connecting the two ends in a loop-like shape, formed on an upper face of a dielectric base body in a rectangular parallelepiped shape having the upper face and a lower face in a square shape in parallel with each other, a grounding conductor film extending in a planar shape formed on the lower face of the dielectric base body, and feeding conductor films and respectively connected to the two ends of the radiating conductor film 12. The feeding conductor films extend in the up and down direction in parallel with each other one of which is connected to the grounding conductor film, are formed on a side face of the dielectric base body 11. The antenna device has high directivity and efficiently transmits and receives electromagnetic waves used in communication.
