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： A surface mount type antenna includes a loop-shaped fed radiation electrode provided on a substrate, and a non-fed radiation electrode is arranged close to the fed radiation electrode with a gap provided therebetween. One end side of the non-fed radiation electrode is grounded, and the other end side is an open end. A signal is sent to the non-fed radiation electrode from the fed radiation electrode by electromagnetic coupling to perform a resonant operation. The fed radiation electrode and the non-fed radiation electrode generate a double-resonant state. The double resonance extends the frequency band. When the fed radiation electrode and the non-fed radiation electrode are provided on the substrate to define an antenna, the size of the antenna is greatly reduced.

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： 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.
摘要翻译：在表面贴装天线的馈电辐射电极中，在高阶模式（二阶模式）中的最大谐振电流部分局部地形成诸如曲折图案的串联电感分量，以局部形成串联电感分量其中使得最大谐振电流部分具有比其他部分更大的每单位物理长度的电长度。这使得可以在大范围内控制基模中的谐振频率与高阶模式中的谐振频率之间的差异。此外，可以通过改变曲折图案的线数或线间距离来改变基本模式中的共振频率，从而改变二阶模式中的谐振频率，从而改变系列的值电感分量。因此，可以容易且有效地设计具有满足多频带应用要求的频率特性的表面贴装天线，而不必改变基本设计。
