A Kind of New Minimize Technology of Circular Polarization Antenna

This paper propose a new kind of circular polarization antenna, i.e. CPA , composed of fold crossed dipole. The fold dipoles are vertical in space, and there is 90 degree phase difference between their feeding current. With the software CST Microwave StudioR , we conclude that there is almost no difference between fold and non-fold crossed dipole about their properties, except their size, the size of fold crossed dipole is about 50% of non-fold crossed dipole.
