Having studied the transmitarray antennas, it is found that the cells depending on their location on the antenna aperture should have a specific slope in the transmission phase diagram in terms of frequency. The central cell has the most negative slope, and as long as the centre is farther away, the negative slope of the transmission phase diagram in terms of frequency is reduced. Therefore, the ability to change the slope of the transmission phase diagram in terms of frequency in the unit cell is essential. To validate the proposed approach, by providing a suitable unit cell, a typical X-band antenna with an aperture size of 20.55λ 0 2 at 10 GHz has been designed, fabricated, and tested. In order to evaluate the effect of the transmit array aperture, the gain enhancement value of the antenna is calculated and maximum gain of 5.9 dBi at 10.5 GHz and a 29.71% 1 dB gain bandwidth is achieved.

Unit cell with flexible transmission phase slope for ultra-wideband transmitarray antennas

A transmission metasurface with polarizationtransforming functionalities is presented. The unit cell is characterized by broad band, low profile and low loss. Due to the asymmetric structure, the proposed metasurface shows different responses to different linear-polarized incidences. For a particular linear-polarized incidence, the polarization direction of transmitted waves will be rotated by 90° in 3.72–8.28 GHz with high polarization conversion ratio (PCR). However, for the orthogonal-polarized ones, the incidence will be reflected totally and the polarization remains. The operating mechanism of the proposed metasurface is analyzed both by theoretical investigations and numerical simulations. Measured results of the fabricated samples are in good agreement with the simulated ones.
