Abstract: 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.

Abstract: 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.
