Zusammenfassung:	The present disclosure relates to non-destructive detection of surface defects in an object,and more particularly to leaky-wave antenna and planar magic tee structures for realising the above. In various embodiments, a sensor for detecting surface defects in an object comprises: a leaky-wave antenna comprising an array of unit cells wherein each unit cell comprises a slotted patch antenna overlaying a slotted substrate integrated waveguide(SIW); a millimetre-wave transceiver; and a circulator communicably coupled between the leaky wave antenna and the millimetre-wave transceiver for controlling transmission and reception of millimetre-wave there between.
