Abstract
In this paper, the design and implementation of a wideband circularly polarized (CP) transmitarray are reported. The receiving/transmitting unit cell is designed by using magneto-electric (ME) dipole with polarization conversion from linearly polarized (LP) to CP. In addition, a full 360-deg geometric phase tuning range can be provided by rotating the transmitting CP element. As a demonstration, a single beam transmitarray is developed by utilizing geometric phase compensation technique. The results verify that the axial ratio performance can be improved within the whole operating frequency band due to the opposite phase response for the dual CP components. Moreover, this methodology can be easily extended to the design of multi-beam CP transmitarray with a cluster of LP feeds.
