Design of circularly polarized folded transmitarray antenna
International Conference on Optoelectronic and Microelectronic Technology and Application, 2020In this paper, the method of circularly polarized folded transmitarray antenna (CPFTA) is first proposed and studied based on transmitarray antenna (TA). The special element of TA is proposed to reflect x-polarized waves as a ground, transmit y-polarized waves and convert the y-polarized waves to circular polarized wave with arbitrary phase shift at ...

Antenna-Filter-Antenna Based Transmitarray with Beam-steering Capability
2019 IEEE International Conference on Microwaves, Antennas, Communications and Electronic Systems (COMCAS), 2019An original approach of an antenna-filter-antenna based transmitarray which consists of the unit cells with 1-bit phase quantization is considered. Each unit cell represents a passive receiver-transmitter structure with integrated phase-shifter, which can take either of two coding states corresponding 180° phase difference between the states.
