摘要:
An antenna apparatus includes a rectangular conductor plate having a longitudinal length of one fourth the wavelength of a signal having an operating frequency and a line-shaped inverted F antenna mounted thereon. The line-shaped inverted F antenna is disposed at one end in the longitudinal direction of the conductor plate so as to be perpendicular to the longitudinal sides of the conductor plate.
