MOBILE SATELLITE ANTENNA

摘要

PURPOSE: A mobile satellite antenna is provided to improve the receiving sensitivity of the mobile satellite antenna by receiving a satellite signal from various directions. CONSTITUTION: A mobile satellite antenna includes a reflecting plate(30), a plurality of metal patches(20), a feeding pattern(40), and an LNA(Low Noise Amplifier) circuit portion. The metal patches(20) are vertically formed on an upper surface of the reflecting plate(30). The feeding pattern(40) is formed on an insulating layer which is adhered on a back side of the reflecting plate(30). The feeding pattern(40) is connected to an arbitrary patch through a feeder. The LNA circuit portion amplifies a satellite signal received from the feeding pattern(40) and transfers the amplified signal to a receiver. The reflecting plate(30), the metal patches(20), the feeding pattern(40), and the LNA circuit portion are installed in an upper case(10) and a lower case(50).
