摘要： An integrated antenna includes a dielectric on which is patterned an antenna element and on which, close to an edge of the dielectric, is also patterned a conductive ground coupling member. The ground coupling member is capable of electricalcoupling with a grounded body surrounding the dielectric to provide a ground for an unbalanced transmission line whose live is connected to the antenna element. The length of the ground coupling member is made such that an integral odd number of quarterwavelengths of signals at each operating frequency are adapted to extend either side of a signal-ground connection point; the length approximates one-half wavelength at the primary operating frequency. By including a second signal feedline to extend in parallel with the ground coupling member and connect with another antenna element, it is possible for the integrated antenna to receive/transmit on at least two frequencies. The invention finds application in integrated antenna structures in which a local ground connection is not readily possible. For instance, the dielectric and grounded body may be a respective window and chassis of a car. Another automotive application involves forming the integrated antenna on a plastic boot lid.
摘要翻译：集成天线包括其上构造有天线元件的电介质，并且在电介质附近的接近电介质的边缘也被图案化为导电接地耦合构件。接地耦合部件能够与围绕电介质的接地体电耦合，以为不平衡传输线路提供接地，该传输线路带电连接到天线元件。接地耦合构件的长度被做成使得在每个工作频率处的整数奇数个四分之一波长的信号适合于延伸信号接地连接点的任一侧; 该长度在主要操作频率处接近二分之一波长。通过包括第二信号馈线与地耦合构件平行延伸并与另一个天线元件连接，集成天线可以在至少两个频率上接收/发射。本发明应用于集成天线结构中，其中本地接地连接不容易实现。例如，电介质和接地体可以是汽车的相应窗户和底盘。另一种汽车应用涉及在塑料行李箱盖上形成集成天线。

摘要： A vehicle antenna is concealed by utilizing, as part of the antenna, an elongated slot normally functioning only for decoration on a metal panel of the vehicle. A second part of the antenna is formed by an antenna element positioned at the slot for transmitting and/or receiving signals through the slot. A basic form of the antenna is a slot antenna in which a wire extends across the slot through or behind an opaque plastic plug fitted in the slot and extending in the plane of the metal panel. Another form has an elongated antenna element extending longitudinally at a central position in the slot. The antenna element may be formed as a metallic strip on a printed circuit board extending behind the slot, and an earth ring may be formed as a surrounding metallic surface that capacitively couples with the metal panel. The slot is used in a dual capacity, providing decorative trim but also forming part of the antenna. Plastic bumper moulding or vehicle trim may have a stem portion that is press-fittable in the slot for retaining the moulding or trim in place on the vehicle, and in such case the stem portion may be a dielectric material to an end of which an antenna element can be fitted. The moulding or trim completely covers the slot, concealing the antenna.
摘要翻译：作为天线的一部分，通过利用通常仅在车辆的金属面板上进行装饰的细长槽来隐藏车辆天线。天线的第二部分由位于时隙处的天线元件形成，用于通过该槽发送和/或接收信号。天线的基本形式是缝隙天线，其中线穿过狭槽穿过插入槽中并在金属面板的平面中延伸的不透明塑料插塞之后或之后延伸。另一种形式具有在槽中的中心位置处纵向延伸的细长天线元件。天线元件可以形成为在槽后面延伸的印刷电路板上的金属带，并且可以形成接地环作为与金属板电容耦合的周围金属表面。该槽用于双重容量，提供装饰装饰，但也形成天线的一部分。塑料保险杠模制或车辆装饰件可以具有可压配合在槽中的杆部分，用于将模制件或装配件保持在车辆上的适当位置，并且在这种情况下，杆部分可以是电介质材料，其端部元件可以安装。模制或装饰完全覆盖了狭槽，隐藏天线。

摘要： An antenna comprises first and second antenna elements 64, 66 mounted on a dielectric sheet 62 with a signal connection 70 to the first element 64 and the second element 66 having a connection 72, proximate to that of the first element, which includes a connection to a proximate vehicle-body ground 54. The first and second connections 70, 72 are connected via a balanced transmission line 60 to signal feed means 50. The signal feed means 50 may be an unbalanced transmission line such as a coaxial cable or a signal amplifier. The balanced transmission line 60 may be a twin wire or twin printed conductive line or a twisted wire pair signal feed with a length of about one-half of the centre operational wavelength of the antenna. The first and second elements 64, 66 may be of about the same length and the first element 64 may be arranged to extend in a direction normal to that of the edge of the dielectric sheet 62. The dielectric sheet 62 may be a glass window of a vehicle. The antenna may operate at GHz frequencies.
