1. An antenna comprising:
- a ground conductor to which a ground potential is applied;
a linear conductor configured to transmit a high-frequency signal;
an insulating layer configured to isolate the ground conductor and the linear conductor from each other; and
a radiation conductor that is connected between the linear conductor and the ground conductor, whereinthe radiation conductor has a first edge and a second edge opposite to the first edge,the radiation conductor is connected to the linear conductor by a first point of connection closer to the first edge than to the second edge,the radiation conductor is connected to the ground connector by a second point of connection closer to the second edge than the first edge,the radiation conductor has a line width larger than a line width of the linear conductor when measured in the same direction,the first edge and the second edge are outside peripheral edges of the radiation conductor, andthe center frequency of a high-frequency signal transmitted through the antenna is determined by a capacitance C1 between the linear conductor and the ground conductor, an inductance L1 of the linear conductor, a capacitance C2 between the radiation conductor and the ground conductor, and an inductance L2 of the radiation conductor.

Abstract
This disclosure provides an antenna having a high degree of design flexibility. In a representative embodiment, the antenna includes a ground conductor to which a ground potential is applied, a linear conductor that transmits a high-frequency signal, an insulating layer configured to isolate the ground conductor and the linear conductor from each other, and a radiation conductor that is connected between the linear conductor and the ground conductor. The radiation conductor has a line width larger than that of the linear conductor between a point of connection to the linear conductor and a point of connection to the ground conductor, and is configured to emit an electric field.
