An antenna (100) for generating radiation includes a primary E-field generating circuit (110, 120) and a secondary E-field generating circuit (130). The primary E-field generating circuit (110-120) generates a primary E-field (152) in response to a source RF signal being applied to the antenna (100). The secondary E-field generating circuit (130) generates a secondary E-field (154), disposed apart from the primary E-field (152), in response to the source RF signal and develops an H-field (156) that is in time phase with the primary E-field (152). This causes the antenna to develop a radiation resistance as an indication of radiation. |
