Abstract (in Japanese) (See Japanese page) 
(in English) When we measure the radiation efficiency of the monopole antenna by the improved Wheeler method which use the waveguide and sliding shorts, we can observe some dips of the efficiency at discrete frequencies. In this report, we introduce a simple transmission line model including the loss of the sliding shorts, analyze the dips of the efficiency, and then propose some techniques for removing the dips.
