    • A top loaded antenna unit is provided for concealed mounting within a vehicle below a covering or panel of dielectric material. The antenna unit includes a top load plate, a ground plate disposed in a spaced relation to the top load plate and electromagnetically coupled thereto through a matching element. The antenna unit additionally includes a dielectric member which is disposed in proximity to the top load plate for shifting resonance frequency of the antenna to a predetermined extent. The top load plate and the ground plate are assembled together with the dielectric member into a unitary structure for mounting within the vehicle below the covering or panel of dielectric material, at which condition resonance frequency of the antenna can be free from being affected from the covering or panel of the vehicle but affected solely from the dielectric member of which effect on the frequency shifting is known. Whereby, the antenna can give stable resonance frequency as intended only in consideration of the dielectric member and without being substantially influenced by other outside environments.
    • 提供顶部加载的天线单元,用于隐藏地安装在介电材料的覆盖物或面板下方的车辆内。 天线单元包括顶部负载板,与顶部负载板隔开设置的接地板,并通过匹配元件与其电磁耦合。 天线单元另外包括电介质构件,其布置在顶部负载板附近,用于将天线的共振频率移动到预定的程度。 顶部负载板和接地板与电介质构件组装成一体的结构,用于安装在介电材料的覆盖物或面板下方的车辆内,在该状态下,天线的共振频率可以不受覆盖物的影响 或车辆的面板,但仅影响其在频移上的影响的电介质构件是已知的。 由此,天线可以仅考虑电介质构件而给出稳定的谐振频率,而不受其它外部环境的显着影响。

    • An asynchronous multichannel signal processing system comprises a transmitter and a receiver. A transmitter is adapted to transmit a signal converted from data being transmitted including address data and control data such that one information unit comprises a plurality of units each including one frequency signal. The receiver is adapted to reproduce the received data by discriminating the frequency component included in the received signal. At that time, a plurality of readings of received data are reproduced in one unit time period of the transmitted signal. If and when the address data included in at least one of the plurality of readings of received data coincides with its own address data of the receiver, the control data is extracted from the received data including the coincided address data.
    • 异步多信道信号处理系统包括发射机和接收机。 发射机适于发送从正被发射的数据转换的信号,包括地址数据和控制数据,使得一个信息单元包括多个单元,每个单元包括一个频率信号。 接收机适于通过识别包含在接收信号中的频率分量来再现所接收的数据。 此时,在发送信号的一个单位时间段内再现接收数据的多个读数。 如果并且当包括在接收数据的多个读数中的至少一个中的地址数据与其自己的接收器的地址数据一致时,则从接收到的数据中提取包括一致的地址数据的控制数据。
