摘要： 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.

摘要： A compact wideband single feed circularly polarized antenna is provided. The circularly polarized antenna may include a ground plane. The circularly polarized antenna may include a radiating patch with an embedded ring-shaped slot. The circularly polarized antenna may include a via that shorts a round section of the radiating patch surrounded by the ring-shaped slot to the ground plane. The circularly polarized antenna may include a coaxial feed. The inner conductive material of the coaxial feed may be connected to the radiating patch and the outer conductive material of the coaxial feed may touch the ground plane. The circularly polarized antenna may include a slit-slotted parasitic square patch.
