%X We report searches for the processes e<sup>+</sup>e<sup>−</sup>→π<sup>+</sup>π<sup>−</sup>π<sup>0</sup>χ<sub>bJ</sub> and e<sup>+</sup>e<sup>−</sup>→ϕχ<sub>bJ</sub> (J=1,2) in the vicinity of the Υ(11020) resonance using energy scan data collected by the Belle experiment at the KEKB collider. We observe e<sup>+</sup>e<sup>−</sup>→ π<sup>+</sup>π<sup>−</sup>π<sup>0</sup>χ<sub>b1</sub> and find evidence for e<sup>+</sup>e<sup>−</sup>→ ωχ<sub>b2</sub> processes for data with center-of-mass energies from 10.96 to 11.05 GeV for the first time. The statistical significance for π<sup>+</sup>π<sup>−</sup>π<sup>0</sup>χ<sub>b1</sub> and ωχ<sub>b2</sub> are 6.1σ and 4.0σ, respectively. We investigate energy dependence of the e<sup>+</sup>e<sup>−</sup>→π<sup>+</sup>π<sup>−</sup>π<sup>0</sup>χ<sub>bJ</sub> cross section and find that it is consistent with production of Υ(10860) and Υ(11020) resonances without significant non-resonant contribution. Assuming e<sup>+</sup>e<sup>−</sup>→ π<sup>+</sup>π<sup>−</sup>π<sup>0</sup>χ<sub>bJ</sub> proceeds via Υ(10860) and Υ(11020), the branching fraction <i>B</i>(Υ(11020)→π<sup>+</sup>π<sup>−</sup>π<sup>0</sup>χ<sub>bJ</sub>)=(8.6±4.1±6.1<sup>+4.5</sup><sub>−2.5</sub>)×10<sup>−3</sup> is measured for the first time, where the first error is statistical, the second is systematic, and the third from the branching fraction of Υ(11020)→ e<sup>+</sup>e<sup>−</sup>. The signals for e<sup>+</sup>e<sup>−</sup>→ ϕχ<sub>bJ</sub> are not significant, and the upper limits of the Born cross sections at the 90% confidence level are 0.6 and 1.0 pb for e<sup>+</sup>e<sup>−</sup>→ ϕχ<sub>b1</sub> and ϕχ<sub>b2</sub>, respectively, for center-of-mass energies from 10.96 to 11.05 GeV.
