This disclosure provides a feed network, an antenna apparatus, and a communication device. A main portion is disposed with a first electric-conductor and a second electric-conductor. In addition, two branch portions are disposed, one end of a first branch portion is electrically connected to the first electric-conductor, and one end of a second branch portion is electrically connected to the second electric-conductor. In this way, when two radiation parts in a same polarization direction of a radiating element are electrically connected to the first branch portion and the second branch portion respectively, a transmission structure of the feed network may feed two radio frequency signals, for example, two equi-amplitude phase-inverted radio frequency signals, into the two radiation parts of the radiating element respectively. The feed network in this embodiment of this application has a simple line, so that space occupied by the feed network in the antenna apparatus is reduced.
