Abstract: An antenna according to an embodiment of the present technology includes a loop-shaped conductor and a structure. The loop-shaped conductor is configured in a loop shape surrounding a first direction and has a gap configured using a predetermined second direction orthogonal to the first direction as a reference. The structure is electrically connected to the loop-shaped conductor and arranged orthogonally to the second direction. Accordingly, it is possible to achieve a reduction of a distance from the human body and a reduction of a clearance from a metal part, and it is very advantageous for downsizing the electronic apparatus. Moreover, it is possible to exhibit high communication performance.

Abstract: A small-sized normal mode helical antenna is provided that is not affected by nearby conductors. The antenna is an antenna including a coil constituting a normal mode helical antenna, an area of a cross section perpendicular to an axis of the coil for a single turn at each end of the coil being less than an area of a cross section perpendicular to the axis of the coil near the coil center.

Abstract: Provided is an electromagnetic wave absorber capable of further expanding applicable objects while reducing a size of a unit structure, and at the same time, improving the degree of freedom in arrangement. An electromagnetic wave absorber 201 includes a substrate 202, a first wiring pattern 203 mounted on one surface of the substrate, and a second wiring pattern 204 mounted on the other surface opposite to the one surface, the first wiring pattern 203 includes a line portion 211 extending in parallel to a direction in which an external electric field is generated, a capacitor portion 212 in which a potential difference is generated by the external electric field, and a first connecting portion 213 and a second connecting portion 214 which connect each of ends of the line portion with the capacitor portion, and the second wiring pattern 204 includes a wire portion 221 which extends in the same direction as the line portion and is arranged at a position opposite to the line portion, and extension portions 222 and 223 that are branched to be bent from ends of the wire portion.
