MINIMIZED ANTENNA APPARATUS

摘要

PURPOSE: A small antenna apparatus is provided to determine a resonance frequency band using a serial capacitor and a parallel capacitor. CONSTITUTION: A small antenna apparatus comprises a feed unit(120) and a transmission unit(140). The feed unit is formed with a rod shape. The transmission unit is separated from the feed unit. The transmission unit resonates the preset frequency band when receiving the power from the feed unit. The transmission unit includes a serial capacitor(141), a conductor(145), and a parallel inductor(143). The serial capacitor is serially connected to the feed unit. The conductor is extended from the serial capacitor. A parallel inductor is connected to the conductor in parallel.
