Abstract

The invention relates to wireless communication apparatus and a chip antenna apparatus. The chip antenna apparatus comprises a cuboid-shaped dielectric substrate, and a first radiation part and a second radiation part which are arranged on the surface of the substrate and are arranged at intervals mutually; the first radiation part comprises a first antenna part for covering the upper surface of the substrate and a first conductor part for covering the side surface perpendicular to the upper surface; the first antenna part is connected with the first conductor part; the second radiation part comprises a second antenna part for covering the upper surface of the substrate and a second conductor part for covering the side surface perpendicular to the upper surface; the second antenna part isconnected with the second conductor part; and the width of the first conductor part is enlarged gradually in a direction far from the upper surface in the adjacent place of the first conductor part and the second conductor part. The impedance of the widened antenna conductor is continuously changed along with frequency changes to be more steady and smoother, thereby gradually lowering sensitivityof the antenna conductor on frequency changes, and ensuring operational stability of the antenna apparatus.
