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 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.

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.
