Abstract:

This paper proposes a new slot lens antenna with a microstrip patch antenna loaded lens structure,that is,the double H-shaped slot coupled feed,to achieve circular polarization excitation.An appropriate dielectric lens antenna structure is adopted in front of the antenna to properly press the antenna beam and improve the gain,VSWR,and axial ratio.The antenna has the advantages of compact structure,simple power supply,and easy manufacturing.

Key words: hyperbolic cylindrical lens antenna;microstrip patch;double H-shaped slot;coupled feed
