Abstract: A system for investigating the internal structure of a human or animal body. The system comprises one or more antennas for transmitting and/or receiving electromagnetic energy into or from the body, each antenna comprising a slot formed in a conductive element, the slot having an external boundary defined by a substantially closed internal edge of the conductive element. A receiver is configured to detect the effect of the body on the passage of the electromagnetic energy by recording one or more signals. A processor is configured to process the signal(s) in order to generate an output indicative of the internal structure of the body. The antenna slot is a continuous slot with no internal boundary, the boundary of the slot being completely defined by the internal edge of the conductive element. Each antenna may further comprise two or more conductive feed lines, each feed line coupling energy to and/or from a respective part of the slot.
