Abstract
The invention presents an antenna element capable of attenuating electric far filed while suppressing attenuation of magnetic near field of electromagnetic field radiated from loop antenna as an application example of antenna element, and a loop antenna and a communication control apparatus of wireless communications medium using the same. The antenna element of the invention comprises a conductor, and a conductive electromagnetic shield disposed on its surface by way of an insulator. The conductive electromagnetic shield has a ground contact, a lead portion, and a plurality of branches, and it is composed so as to determine uniquely the route from an arbitrary point of branches to the ground contact by way of the lead portion.
