1. An antenna arrangement for transmitting and receiving radio signals, comprising a receiver stage and a capacitatively tunable loop having an axis of symmetry and including two halves arranged symmetrically relative to said axis, and a feed-in point positioned on said axis of symmetry wherein radio signals received from the tunable loop can be coupled into the receiver stage in two signal flows symmetrical to each other relative to said axis of symmetry and wherein a signal to be radiated by the tunable loop is splittable at said feed-in point into two signals flowing in two opposite directions relative to the axis of symmetry such that same potential is formed in each half of the tunable loop.
