Zusammenfassung:The invention relates to the technical field of wireless communication, in particular to a duplex antenna. The duplex antenna is a single integrated duplex antenna, specific signals need to be transmitted and received at a specific port and cannot be leaked to another port, the first port is connected with the monopole antenna and used for receiving energy fundamental wave signals, and the second port is connected with the slot antenna and used for transmitting harmonic signals. Isolation between ports is formed through different resonance current modes, an additional duplex filter or a power divider is not needed to achieve duplex work of the antenna, feeder lines of the monopole antenna and the slot antenna are zigzag, and isolation between the ports is increased. The invention provides a pair of duplex antennas which can be provided with port isolation, so that the node area can be further and effectively reduced, and the miniaturization of a wireless sensor network receiving node is realized. 本发明涉及无线通信技术领
