1. An antenna system of a wireless electronic device, comprising:
- a first antenna ring extending around a perimeter of the wireless electronic device;
a second antenna ring extending around the perimeter of the wireless electronic device spaced apart from the first antenna ring;
a first connector portion electrically connecting the first antenna ring to the second antenna ring at the perimeter of the wireless electronic device;
a ground plane in the wireless electronic device, wherein the first and second antenna rings are spaced apart from the ground plane;
a first port at the ground plane configured to feed a first electrical signal to the first antenna ring; and
a first ground element electrically connecting the first antenna ring to the ground plane,wherein a portion of the first antenna ring between the first port and the first ground element and a portion of the ground plane between the first ground element and the first port form a first conductive pattern for the first electrical signal around a first slot, wherein the first slot is a first nonconductive space.

Abstract
Wireless electronic devices may include a ground plane, a double ring antenna and non-cellular antennas integrated within the double ring antenna. The double ring antenna may comprise first and second metal rings around the perimeter of a ground plane to operate as MIMO cellular antennas. At least one non-cellular antenna, such as a MIMO Wi-Fi antenna, may be integrated between the first and second metals rings on one or more sides of the wireless electronic device.

8. A wireless electronic device, comprising:
-
a ground plane; a double ring antenna, comprising, a first antenna ring extending around a perimeter of the ground plane and spaced apart from the ground plane, a second antenna ring extending around the perimeter of the ground plane and spaced apart from the first antenna ring and the ground plane, a first connector portion electrically connecting the first antenna ring to the second antenna ring; a transceiver circuit coupled to the ground plane and configured to provide a first electrical signal and a second electrical signal to ports of the double ring antenna; a first port at the ground plane configured to feed the first electrical signal from the transceiver circuit to the first antenna ring; and a first ground element electrically connecting the first antenna ring to the ground plane, wherein the first antenna ring between the first port and the first ground element and the ground plane between the first ground element and the first port form a first conductive pattern for the first electrical signal around a first slot, wherein the first conductive pattern and the first slot define a first cellular antenna configured to radiate a third electrical signal responsive to the first electrical signal. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17)
