Abstract
An electronic circuit for a mobile device, including: a power divider and a hybrid antenna array coupled to a transceiver via the power divider. The hybrid antenna array including a steering beam phased array antenna provided on the front-end module, and a fixed beam antenna provided on the front-end module or distributed on PCB. The fixed beam antennas can be used in space constrained areas of a mobile devices, such as those adjacent to a display on one side of the device, while larger steering beam phased array antennas are used on the back side of a device.
