Abstract
A planar antenna includes: a radiating element; a flexible dielectric film portion; a power feeder line provided for the dielectric film portion, and configured to feed power to the radiating element; a first ground conductor facing against the radiating element; and an antenna base having a dielectric layer disposed between the radiating element and the first ground conductor. The dielectric film portion extends from a side surface of the antenna base. The dielectric layer is thicker than the dielectric film portion.
Claims8
A wireless module comprising:
- a radiating element;
- a flexible dielectric film portion;
- a power feeder line provided for the dielectric film portion, and configured to feed power to the radiating element;
- a first ground conductor facing against the radiating element;
- an antenna base having a dielectric layer that is disposed between the radiating element and the first ground conductor, the dielectric layer having a laminated structure in which a plurality of films is continuously laminated, the dielectric film portion extending from a side surface of the antenna base toward an outside of the antenna base;
- and
- a wireless unit to which the power feeder line is connected,
- wherein the laminated structure includes a main layer provided with the dielectric film portion and one or more subsidiary layers laminated on a region of the main layer excluding the dielectric film portion.
