摘要： An antenna includes a radiation electrode, with one end thereof being connected to a conductive portion located on a front or back surface of a board. The radiation electrode extends outward from the conductive portion starting from the connected end, is bent around an edge of the board, and extends to a side opposite to the side of the starting point with a space therebetween. The other end of the radiation electrode is not connected to the conductive portion so as to function as an open end. Since the radiation electrode extends from one side to the other side of the board, the electric length of the radiation electrode can be increased. Accordingly, the size and thickness of the radiation electrode can be reduced while keeping a set resonance frequency. Also, since a space defined by the board and the radiation electrode can be increased, the gain is greatly improved and the bandwidth is significantly broadened.
摘要翻译：天线包括辐射电极，其一端连接到位于电路板前表面或后表面上的导电部分。辐射电极从导电部分向外延伸，从连接的端部开始，围绕板的边缘弯曲，并延伸到与起始点相对的一侧，其间具有空间。辐射电极的另一端未连接到导电部分，以起到开放端的作用。由于辐射电极从板的一侧延伸到另一侧，所以可以增加辐射电极的电长度。因此，可以在保持设定的共振频率的同时减小辐射电极的尺寸和厚度。另外，由于可以增加由板和辐射电极限定的空间，所以增益大大提高，带宽显着扩大。

摘要： A surface-mounted type antenna which facilitates the realization of the widening of the frequency band, and a communication device including it. In this antenna, the strong electric-field regions of a power supplied first radiation electrode and a power non-supplied second radiation electrode are disposed adjacent to each other with a spacing therebetween, and simultaneously the high current regions of these radiation electrodes are disposed adjacent to each other with a spacing therebetween. By variably adjusting the quantity of the electric-field coupling between the strong electric-field regions of the first radiation electrode and the second radiation electrode, and by variably adjusting the quantity of the magnetic-field coupling between the high current regions of these radiation electrodes, both the quantities of the electric-field coupling and the magnetic-field coupling are set to conditions suited for the dual resonance. A superior dual resonance is thereby achieved.

摘要： A radiation electrode is formed on the upper face of the substantially columnar dielectric substrate. Feed electrodes for a fundamental mode and for a higher mode are formed on the side peripheral face of the dielectric substrate. Power is supplied through the respective feed electrodes to the radiation electrode via capacitive coupling. The radiation electrode has both of the functions in the fundamental and higher modes. Thus, the circular polarized wave antenna can be reduced in size. Furthermore, since a capacitive feeding system is employed as described above, the respective resonance frequencies in the fundamental and higher modes can be easily adjusted and set at predetermined frequencies. Also, the circularly polarized wave characteristics in the fundamental and higher modes can be easily enhanced, respectively.

摘要： A compact surface-mounted antenna having a wide frequency band. In the surface-mounted antenna, a first radiation electrode is formed on the left-half region of the upper surface of a base dielectric substrate. A multi-layer dielectric substrate is laminated on the upper surface of the base dielectric substrate to be bonded and fixed thereto. A second radiation electrode is formed on the right-half region of the upper surface of the multi-layer dielectric substrate. The first and second radiation electrodes are not vertically opposed to each other. Opposing edges of the first and second radiation electrodes are oblique lines. A feeding signal of a signal source is supplied to the first radiation electrode by coupling from a feeding connection electrode, and then, is supplied to the second radiation electrode from the first radiation electrode by another coupling between the first and second radiation electrodes. A direction in which the first radiation electrode excites is set to be substantially perpendicular to a direction in which the second radiation electrode excites.
