This paper demonstrates that in microwave hyperthermia, while a single open-ended rectangular waveguide antenna (ORWA) applicator may be used for the treatment of only the superficial cancerous tumours, an ORWA array may possibly be used for heating of deep-seated tumours. By applying the Kirchhoff-Huygens principle and scalar theory of diffraction, the near-field distributions due to a single ORWA and ORWA arrays in an adjacent homogeneous human muscle are calculated. ORWA array applicators have better performance because of their field focusing effect which depends on the number of elements
