MIMO antenna and methods

---

Abstract

---

An antenna structure that provides spatial multiplexing capabilities. In one embodiment, the antenna comprises two antenna components with a substrate and radiator, the components being located on opposite sides of the circuit board of a radio device. Each antenna component operates in combination with the ground plane of the radio device to form a partial antenna, the operating band of which is below the frequency of 1 GHz. The ground plane and the feed points of the partial antennas are arranged so that the ‘dipole axes’ of the partial antennas have clearly different directions at the frequencies of said operating band.
