An antenna for a portable radio communication device is constructed with a conductive shield plate provided in a casing made of resin and shaped to be worn on a human body. The shield plate is capacitively coupled with a part of the human body to operate as an antenna element. A conductive cover of a battery is disposed in the casing to operate as the other antenna element. The antenna elements thus form an electric field-type dipole antenna. The conductive cover of the battery may also be capacitively coupled with the other part of the human body, so that the antenna operate as a loop antenna which uses the human body. The electric field-type antenna may be combined with a magnetic field-type antenna to make the directivity of the antenna to be isotropic.
