PURPOSE: An automobile antenna including a harmonics removal switch is provided to prevent signal interference by including a PIN diode blocking an RF signal received at an automobile antenna. CONSTITUTION: An automobile(110) receives an RF signal. An RF signal operates in a specific frequency range transmitted from a base station. A low noise amplifier(120) amplifies the RF signal received at the automobile antenna. A PIN diode(131) forms a reception path transmitting the RF signal to the low noise amplifier. The PIN diode blocks the RF signal unless DC power is applied. |
