Ion Bernstein wave (IBW) heating experiments are performed with a poloidally phased antenna. Between two kinds of poloidal phasing, no difference is found with the heating effect which is expected from the mechanism of heating presented previously. The significant differences due to the difference of poloidal phasing are found in observations of electron density variation, emission intensities of impurity lines and scrape-off layer plasma. All the results show that the poloidal phasing brings about variations of particle transport, and a ponderomotive effect of the antenna near-field might be the most probable mechanism. The phasing effect should be considered on an intense radio frequency (RF) injection by poloidally aligned antenna elements.
