摘要： Disclosed embodiments provide a feed circuit, an antenna device, a communication device, and a communication system that are configured to improve passive intermodulation (PIM). In the feed circuit, phase shift elements are disposed along a plurality of parallel branches to cancel PIM caused by semiconductor components in semiconductor modules in the branches.
