Simulations have been made by using the Wakefield Solver of CST Particle Studio. And the result of this influence at different ratio of beam horizontal width σ and the BPM inner diameter a has been obtained. This kind of influence has been observed in the stripline BPMs in the transfer line of Beijing Positron Electron Colliders upgraded version II (BEPCII). The research is useful when we design the inner diameter of the stripline BPMs for ultra-relativistic electron beam, meanwhile it provides reference to distinguish the invalid ones from the measuring results obtained by the stripline BPMs in the ultra-relativistic situation.
