    • A signal reception circuit includes a main antenna which receives signals in at least two predetermined reception frequency bands. A sub-antenna receives a signal in one of the reception frequency bands of the main antenna. A filter for interrupting a signal in the same frequency band as the reception frequency band of the sub-antenna is provided on a transmission line of a reception signal of the main antenna. A filter reflection signal in the same frequency band as the reception frequency band of the sub-antenna is induced in the sub-antenna, due to the antenna coupling thereof. The phase of the filter reflection signal is adjusted by a phase shifter between the main antenna and the filter, so that the induced signal of the sub-antenna is in phase with the reception signal of the sub-antenna. As a result, the level of the composed signal of the induced signal and the reception signal and is to be transmitted from the sub-antenna to a signal processing unit is greatly improved.
    • 信号接收电路包括在至少两个预定接收频带中接收信号的主天线。 子天线在主天线的接收频带之一接收信号。 在主天线的接收信号的传输线上设置用于中断与子天线的接收频带相同频带的信号的滤波器。 由于天线耦合,在子天线中感应与子天线的接收频带相同频带的滤波器反射信号。 滤波器反射信号的相位通过主天线和滤波器之间的移相器来调节,使得子天线的感应信号与子天线的接收信号同相。 结果,感应信号的合成信号和接收信号的电平将从子天线发送到信号处理单元大大提高。

    • A surface mount antenna includes a substrate and a radiation electrode (having a predetermined resonance frequency) disposed on the substrate. An electrode is formed to cover four continuously connected surfaces including the front surface, the front end surface, the rear surface and the rear end surface of each substrate.

Here, the slit is arranged in a direction intersecting a direction &agr; connecting the two end surfaces. Subsequently, the dielectric substrate is cut into a plurality of portions along the direction &agr;, thus producing a plurality of surface mount antennas each including a substantially rectangular substrate and a radiation electrode formed essentially surrounding an outer circumference of the substrate.
