Abstract
An antenna apparatus includes a carrier, an impedance tuning mechanism corresponding in position to the carrier, and an antenna mechanism that is disposed on the impedance tuning mechanism. The impedance tuning mechanism includes a grounding layer disposed on the carrier and an impedance tuning layer spaced apart from the grounding layer. Moreover, a projection region defined by orthogonally projecting the impedance tuning layer onto the grounding layer is located inside of an outer edge of the grounding layer. The impedance tuning layer has at least one elongated slit recessed from an outer contour thereof to a center thereof. The antenna mechanism is applied to a center frequency. A thickness of the impedance tuning mechanism is within a range from 0.4% to 25% of a wavelength corresponding to the center frequency.
