摘要： In a multi-resonance antenna, at an open end of a radiation electrode of a feeding element and an open end of a radiation electrode of a parasitic element capacitance loading electrodes and ground electrodes are arranged opposite to each other. In the opposing portions, electric-field deflectors are provided, thus reducing the electric-field coupling between the feeding element and the parasitic element.

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： An antenna apparatus includes a dielectric base, and a plurality of feeding-radiating elements having different resonance frequencies, each including a feeding electrode and a radiating electrode which are disposed on surfaces of the base. A stub with a common feeding point is disposed on a mounting substrate which supports the base. The feeding electrodes of the feeding-radiating elements are connected to matching points of the stub, thereby achieving impedance matching for each of the feeding-radiating elements.

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： 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.

摘要： A multi-band surface-mounted antenna is formed by disposing a feeding element and a non-feeding element with a distance therebetween on a dielectric base member. The feeding element is formed by extending a feeding radiation electrode from a feeding terminal. The non-feeding element is a branched element formed by branching and extending a first radiation electrode and a second radiation electrode of the non-feeding side from a ground terminal side. The single surface-mounted antenna includes the three radiation electrodes. Thus, the antenna can be easily adapted to multi-bands. In addition, the resonance waves of the three radiation electrodes can be controlled mutually independently. As a result, only a frequency band selected from a plurality of required frequency bands is brought into a multi-resonance state so that the frequency band can be broadened.

摘要： Power non-supplied side radiation electrode 3 and power supplied side radiation electrode 4 are formed on the surface of a dielectric substrate 2 with a space therebetween. A permittivity adjusting material portion 8 is provided in the space S which is situated between the power non-supplied side radiation electrode 3 and the power supplied side radiation electrode 4, and in which a capacity occurs. The permittivity adjusting material portion 8 has a lower permittivity than that of the dielectric substrate 2, which causes the permittivity between the power non-supplied side radiation electrode 3 and the power supplied side radiation electrode 4 to be lower than that of dielectric substrate 2, and weaken the capacitive coupling between the power non-supplied side radiation electrode 3 and the power supplied side radiation electrode 4.

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 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.
