摘要： An antenna-electrode structure includes a feeding radiant-electrode and a grounded portion arranged such that an open-end of the feeding radiant-electrode defines a capacitance to the grounded portion therebetween, and a non-feeding radiant-electrode arranged to electromagnetically couple the feeding radiant-electrode. The non-feeding radiant electrode is arranged such that an open-end thereof defines a capacitance to the grounded portion therebetween to produce a dual-frequency resonance state together with the feeding radiant-electrode. In response to a signal supplied from a signal-supply source, the feeding radiant-electrode performs an antenna action and the non-feeding radiant-electrode in turn performs an antenna action by signal transmission from the feeding radiant-electrode, such that by being excited from these actions, the grounded portion also performs an antenna action. Because of the antenna action of the grounded portion, the sizes of the feeding radiant-electrode and the non-feeding radiant electrode are reduced.

摘要： This disclosure provides a high-frequency dielectric attachment capable of suppressing a decrease in Q value of a high frequency circuit and achieving a great adjusting effect. The high-frequency dielectric attachment is a laminate of an insulating sheet layer, adhesive layer, and a dielectric sheet layer. The insulating sheet layer forms an outermost layer of the laminate, and the adhesive layer and dielectric sheet layer are arranged in sequence below the insulating sheet layer. The width of the dielectric sheet layer is smaller than each of the width of the insulating sheet layer and the width of the adhesive layer. The adhesive layer projects beyond the dielectric sheet layer in the width direction.

The position of a capacitance-loading portion α is set in advance between the feed end and the open end of the feed radiation electrode. A capacitance-loading conductor is connected to one or both of the feed end and the capacitance-loading portion α of the feed radiation electrode. The capacitance-loading conductor forms a capacitance for adjusting a resonant frequency in the fundamental mode between the feed end and the capacitance-loading portion α.

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.

An outer side surface of the dielectric base member along an edge of one end of the circuit board defines a side surface. A feed electrode is provided in the non-ground region of the circuit board or outside the circuit board such that the feed electrode is disposed along side surfaces of the dielectric base member. One end of the feed radiation electrode defines a feed end connected to the feed electrode, and the other end of the feed radiation electrode defines an open end. The feed radiation electrode has a configuration in which a current path extending from the feed end to the open end has a loop shape so as to be provided on at least the side surface and an upper surface of the dielectric base member. A feed radiation electrode portion formed on the side surface of the dielectric base member 6 forms a capacitance between the feed radiation electrode portion and the feed electrode for improving antenna characteristics.

摘要： In a feeding radiation electrode of a surface mount antenna, a series inductance component such as a meander pattern is formed locally in a maximum resonance current part in a high-order mode (second-order mode) so as to locally form a series inductance component therein thereby making the maximum resonance current part have a greater electrical length per unit physical length than the other parts. This makes it possible to control the difference between the resonance frequency in a fundamental mode and the resonance frequency in the high-order mode over a large range. Furthermore, it is possible to vary the resonance frequency in the second-order mode independently of the resonance frequency in the fundamental mode by varying the number of lines or the line-to-line distance of the meander pattern thereby varying the value of the series inductance component. Thus, it is possible to easily and efficiently design a surface mount antenna having a frequency characteristic which satisfies requirements needed in multi-band applications without having to change the basic design.
