Abstract:
Antenna structures and methods of operating the same of an electronic device are described. One apparatus includes an antenna structure comprising four antenna elements, a RF circuit, and a MIMO RF circuit coupled between the antenna structure and the RF circuit. The MIMO RF circuit may include a pair of diplexers; and a pair of switches. The RF circuit is operable to cause a first antenna element of the four antenna elements to radiate and receive electromagnetic energy in a first frequency range via the MIMO RF circuit and the RF circuit is operable to cause a remaining three antenna elements of the four antenna elements to receive electromagnetic energy in the first frequency range via the MIMO RF circuit to support 4×4 DL MIMO.
