Abstract
Official abstract text for this publication.
A wireless device includes an antenna that has a planar shape and radiates a radio signal toward another wireless device, and a chassis housing the antenna and having an outer peripheral portion placed to face the antenna. Multiple distances between a surface of the outer peripheral portion and the antenna are non-uniform.
First claim
Opening claim text (preview).
What is claimed is: 1. A wireless device comprising: an antenna having a planar shape and which, in operation, radiates a radio signal; and a chassis having an outer peripheral portion and housing the antenna with a first side of the outer peripheral portion facing the antenna, a second side of the outer peripheral portion opposite from the first side including a plurality of projections each having a height that is about one-fourth of a wavelength of the radio signal, wherein multiple non-uniform distances are formed between a surface of the second side of the outer peripheral portion and the antenna along a direction perpendicular to the planar shape of the antenna. 2. The wireless device according to claim 1 , wherein the projections each have a triangular cross-sectional shape. 3. The wireless device according to claim 1 , wherein the projections are arranged in a line. 4. The wireless device according to claim 1 , wherein the projections are arranged in a dot lattice. 5. The wireless device according to claim 1 , wherein a distance between adjacent projections is about one-tenth or more of a wavelength of the radio signal. 6. A wireless device comprising: an antenna having a planar shape and which, in operation, radiates a radio signal; and a chassis having an outer peripheral portion and housing the antenna with a first side of the outer peripheral portion facing the antenna, a second side of the outer peripheral portion opposite from the first side including a plurality of projections separated by a distance that is about one-tenth or more of a wavelength of the radio signal, wherein multiple non-uniform distances are formed between a surface of the second side of the outer peripheral portion and the antenna along a direction perpendicular to the planar shape of the antenna. 7. The wireless device according to claim 6 , wherein the projections each have a triangular cross-sectional shape. 8. The wireless device according to claim 6 , wherein the projections are arranged in a line. 9. The wireless device according to claim 6 , wherein the projections are arranged in a dot lattice.
