A planar dual-mode UWB antenna design for an indoor MIMO communication system

This paper presents the design of a planar UWB dual-mode antenna, which can radiate two orthogonal modes for data transmission through two subchannels simultaneously. An optimized theoretical radiation pattern has been synthesized for a typical indoor office scenario, and this is used as a basis to design a corresponding real world antenna. Since the antenna is expected to be used on a handheld device such as a cellphone or laptop, the antenna is required to be flat and sufficiently small.
