A New Kind of Circular Polarization Leaky-Wave Antenna Based on Substrate Integrated Waveguide

الملخص EN

A new kind of circular polarization leaky-wave antenna with N-shaped slots cut in the upper side of substrate integrated waveguide (SIW) is investigated and presented.

The radiation pattern and polarization axial ratio of the leaky-wave antenna are studied.

The results show that the width of N-shaped slots has significant effect on the circular polarization property of the antenna.

By properly choosing structural parameters, the SIW based leaky-wave antenna can realize circular polarization with excellent axial ratio in 8 GHz satellite band.
