1. A wireless apparatus comprising:
- an antenna;
a circuit board comprising a wireless communication circuit that is connected to the antenna; and
a resin molded housing that accommodates the circuit board,wherein a linear conductor extends from a ground of the circuit board,the entire antenna is accommodated inside the housing and is disposed between the circuit board and an attachment surface of the housing,the conductor is disposed on a same plane as the circuit board or is disposed opposite to the antenna with the circuit board between the antenna and the conductor,the antenna extends, from a connection to the circuit board, along an inner side of a wall of the housing in a first direction,the conductor extends, from the ground, along the inner side of the wall of the housing in a second direction, which is opposite to the first direction, andthe antenna extends substantially perpendicular to the circuit board and is bent by approximately 90 degrees to extend parallel to the circuit board, and a distance between the circuit board and a portion of the antenna which extends parallel to the circuit board is based on a frequency of a carrier that is used in wireless communication,wherein a sensor, a speaker, and a battery adapted to supply power to the wireless communication circuit of the circuit board are provided in the housing,the sensor, the speaker, and the battery do not overlap one another when seen from the attachment surface, andthe antenna is bent not to interfere with the sensor and the battery.
