In order to optimize the structure design of reverberation chamber, electromagnetic simulation software FEKO that based on MOM is used to calculate the electromagnetic field of reverberation chambers with different emission antenna configuration. Effects of emission antenna kind and position arrangement on field performance of reverberation chamber are studied. The results show that the field performance of reverberation chamber could be improved remarkably through select appropriate emission antenna and appropriate antenna position design.
