Abstract
An antenna apparatus includes: an antenna pattern unit receiving a radio frequency (RF) signal; a first ground unit; and a tunable switch unit electrically connecting the first ground unit to the antenna pattern unit and moving a RF signal band of an antenna when power is applied to the antenna apparatus from a power supplier.
Claims13
An antenna apparatus comprising:
- an antenna pattern unit receiving a radio frequency (RF) signal;
- a first ground unit;
- and
- a tunable switch unit electrically connecting the first ground unit to the antenna pattern unit and moving a RF signal band of an antenna when power is applied to the antenna apparatus from a power supplier,
- wherein the tunable switch unit includes a power distributor provided with at least two resistances, and the power distributor distributes the power applied to the antenna apparatus from the power supplier corresponding to a resistance of the at least two resistances,
- wherein the tunable switch unit further includes a power supply stabilization circuit which is configured with a resistance, an inductor, and a capacitor, and the power supply stabilization circuit allows power supplied from the power supplier to be stably applied to a controller, and
- wherein the tunable switch unit further includes a controller controlling the first ground unit and the antenna pattern unit to be connected to each other or disconnected from each other according to whether the power is applied to the antenna apparatus from the power supplier.
