In　this　paper,　a　single　null　compensation　dipole　antenna　for　Wi-Fi　band　(2.4　GHz)　is　developed.　The　antenna　is　fed　by　the　parallel　transmission　lines,　and　its　radiation　unit　consists　of　a　printed　dipole　antenna　and　a　Yagi　antenna.　The　proposed　antenna　has　three　layers.　The　top　and　bottom　layers　are　printed　with　the　dipole　antenna　and　the　driver　arm　of　the　Yagi　antenna.　The　director　and　the　reflector　of　the　Yagi　antenna　are　placed　on　the　middle　layer.　The　three　layers　are　separated　by　two　FR-4　substrates.　This　antenna　satisfies　the　omnidirectional　radiation　characteristic　in　its　H　plane　and　can　compensate　a　null　point　in　the　E　plane.　Simulation　results　show　that　the　10　dB　bandwidth　is　2.32　to　2.46　GHz.　The　maximum　realized　gain　is　1.13　dB　in　the　frequency　band.　The　non-roundness　of　the　H　plane　is　less　than　2　dB,　which　shows　good　omni-directivity.　A　null　point　in　the　radiation　pattern　of　the　E　plane　is　compensated　to　−1.4　dB　at　2.4　GHz,　while　the　other　null　point　of　the　E　plane　remains　below　−15　dB.　The　antenna　has　been　manufactured　and　tested,　and　the　measurement　results　validate　the　design　and　the　simulation　results.　©　2020　Wiley　Periodicals　LLC.
