The high frequency characteristics of W-band planar multi-beam extended interaction resonant cavity are studied. The introduction rules of beam tunnels with planar linear arrangement are discussed. It has been found that the introduction position and the number of beam tunnels are limited by the uniformity of the field. Then the transverse and longitudinal mode distributions of the cavity are analyzed. It shows that large transverse dimension and increased number of gaps will significantly affect the frequency interval, and thus affecting the work stability. The field distribution characteristics of different modes are also analyzed. Based on the field shape factor and a set of complex coefficients, a method to describe the distribution characteristics of the field is established.
