Abstract:
1. An antenna apparatus, comprising: an antenna element including a receiving unit to receive a radio wave; a circuit board on which an amplifier circuit to amplify an input signal sent from the antenna element is formed; an input pin to connect the receiving unit with the amplifier circuit; and a shield cover to cover the amplifier circuit on the circuit board, the shield cover shielding the amplifier circuit from a disturbing wave, wherein the input pin penetrates through the circuit board and is connected to the amplifier circuit by soldering, so as to structure an input unit of the amplifier circuit, wherein an ascertainment aperture is provided in the shield cover, the ascertainment aperture being positioned such that the input unit can be observed from outside of the shield cover, wherein the ascertainment aperture is formed by bending a portion of the shield cover to an inner side of the shield cover, and wherein the bent portion is disposed as a wall in a position between the input unit and an output unit of the amplifier circuit, wherein the output unit outputs a signal amplified by the amplifier circuit.
