Active antenna capable of wireless signal transmission and reception and mobile communication terminal having the same
摘要：
An active antenna capable of transmitting and receiving a wireless signal of a low frequency band and a mobile communication terminal having the active antenna, are provided. The active antenna includes an antenna element (10) which transmits and receives a wireless signal, a filter (20) which filters the wireless signal being received at the antenna element such that a wireless signal belonging to a frequency band lower than the operating frequency of the antenna element is passed, and an amplifier (30) which amplifies the wireless signal being passed through the filter. As a result, the size of the antenna can be greatly reduced, by the use of an active antenna which receives wireless signals of low frequency bands. Additionally, a more compact mobile communication terminal can be provided, because wireless signal of both high frequency bands and low frequency bands can be transmitted and received at one antenna.
摘要（中）：

能够发射和接收低频带和具有该有源天线的移动通信终端的无线信号的有源天线，提供了。 有源天线包括在发送和接收无线信号，一个滤波器天线元件（10）（20），其滤波器在天线元件搜索正在接收的无线信号确实属于频带-低于的工作频率的无线信号 天线元件通过，并在放大器（30）放大该无线信号通过过滤器传递。 其结果是，天线的尺寸可大大降低，通过使用有源天线，其接收低频带的无线信号的。 此外，更紧凑的移动通信终端可以被提供，因为这两个高频带和低频带的无线信号可以是反式mitted和在一个天线接收。
