  • Patent number: 8587480
    Abstract: The present invention provides a patch antenna having a dielectric layer that is composed of one dielectric film, has one or more holes formed therein by punching, and is provided between a patch and a ground plate, and a method of manufacturing the patch antenna. Since the patch antenna uses a dielectric material having a low relative dielectric constant (a low dielectric material), it is possible to reduce the size of a patch antenna and improve productivity.

  • Publication number: 20100097272
    Abstract: An air gap for minimizing a dielectric constant is formed between dielectric blocks having conductor patterns in order to minimize interference between conductor patterns, thereby providing a slim internal antenna that has a wide bandwidth in a low frequency band as well as in a high frequency band. According to the present invention, it is possible to obtain an antenna that simply and quickly obtains desired characteristics by easily adjusting the thickness of the air gap. Further, the internal antenna is formed by layering dielectric blocks that have conductor patterns. Accordingly, while maintaining the interconnection between the conductor patterns, the internal antenna can change resonant frequency thereof into low frequency as compared with an antenna having the same volume of a dielectric. That is, it is possible to effectively reduce the size of an antenna without significantly affecting the characteristics of the antenna.
