no. 2 example

[0096] 12 to 14 show a second embodiment according to the invention. The feeding terminal 12 according to the second embodiment uses a spring connector 12A as a part of the feeding terminal 12 . The antenna element 1 is connected to the wireless circuit of the substrate 20 through a spring connector 12A (cf. Figure 5 ). Other configurations and operating effects are based on Figure 5 The configuration and operation effects are the same as those of the illustrated embodiment, and detailed explanations are omitted here.

no. 3 example

[0098] Figure 15 A third embodiment of the invention is shown. In the third embodiment, a feeding terminal 13 forming a part of feeding means is provided in the antenna element 1 . The feeding terminal 13 is planar. The substrate 20 is provided with a planar feed connector 14 . The feed connector 14 is spring-shaped, and the tip of the feed connector 14 is bent into a V shape.

[0099] According to the third embodiment, since the feed connector 14 forming a part of the connection unit is connected to the feed terminal 13 , the wireless circuit of the substrate 20 is connected through the feed connector 14 . The feed connector 14 is pushed toward the feed terminal 13 . Other configurations and operating effects are based on Figure 5 The configuration and operation effects of those of the illustrated embodiment are the same. Therefore, detailed description is omitted here.

no. 4 example

[0101] Figures 16A to 16C , 17 and 18 show a fourth embodiment of the present invention. In a fourth embodiment, one or both of the two antenna elements 1 and 2 according to the first embodiment are curved. For example, in Figure 16C In the antenna element 2 shown, the planar pattern of the antenna element 2 is meandered.

[0102] In the fourth embodiment, the meandering antenna element 2 enables setting a desired frequency. Such as Figure 16C As shown, when the antenna element 2 is bent in a meandering pattern, the actual size of the antenna element 2 can be compared to Figure 1C The case shown in is longer (longer wavelength), thus reducing the frequency.

[0103] In another variation, the antenna elements may be curved in a three-dimensional array. The remaining configuration and operation effects are the same as Figure 5 The configuration and operation effects of those of the illustrated embodiment are the same. Therefore, detailed description is omitted here....

Abstract

Two antenna elements are planar and stored in a housing. An antenna element is arranged with the antenna faces of the antenna elements orthogonal to the plane of the substrate. The shape, interval, etc. of the antenna element depend on an available frequency. The length of an electric field vector generated between the substrate and the antenna element becomes longer as the antenna element is farther from the substrate. The frequency corresponding to the electric field vector changes corresponding to the radio signal frequency, that is, higher or lower. That is, in the above-mentioned antenna structure, the band of the frequency response is broader. Therefore, in the above-mentioned antenna structure, the frequency response band can be increase and space can be saved in storing an antenna in a housing using a simple structure in which the antenna face of an antenna element is arranged orthogonal to the plane of the substrate.

Description

technical field [0001] The present invention relates to an antenna structure and a communication device, in particular, the present invention relates to an antenna structure and a communication device for improving the space efficiency of an antenna. Background technique [0002] Due to the improved performance of mobile phones, conventional communication devices such as mobile phones, antennas suitable for 2G (second generation mobile phones), 3G (third generation mobile phones), etc. have been proposed (refer to Patent Document 1: Japanese Patent Japanese Patent Laid-Open No. 11-340731). [0003] 2G refers to second generation mobile phones, and corresponds to a PDC (Personal Digital Cellular) system or a GSM (Global System for Mobile Communications) system, etc. using digital technology. Second generation mobile phones use the frequency band of 800 to 900 MHz. [0004] 3G refers to third-generation mobile phones, and corresponds to a CDMA (Code Division Multiple Access)...
