“…A detailed antenna loss budget (spillover, transmission loss of TA, phase error loss, and tapering, etc) for both the bands is provided in table 4. The performance comparisons of the proposed TA and other TAs are shown in table 5 [17,19] presents TAs operating at dual-band, but the elements cannot achieve independent phase and amplitude control. Moreover, compared with the TAs proposed in [14,15] with independent phase (c) yoz plane at 13.12 GHz, (d) xoz plane at 13.12 GHz, (e) yoz plane at 14.1 GHz, (f) xoz plane at 14.1 GHz, (g) yoz plane at 15.12 GHz, (h) xoz plane at 15.12 GHz.…”

In this paper, a novel transmitarray (TA) element with independent control capability of amplitude and phase under dual-band dual-polarized operation is proposed. By changing the physical size of the TA element, the phase variation of the element can cover 360° at two bands. Moreover, the phase change of the frequency band is less than 30° when the phase of the other band is changed. Meanwhile, a higher maximal transmission amplitude can be maintained when varying the phase. Amplitude modulation is achieved by rotating the TA element. Utilizing the proposed TA element, a dual-band dual-linear polarization (LP) TA with low side lobe level (SLL) operating at 12.5 GHz and 14.25 GHz is designed. The SLL can be decreased by amplitude modulation of the elements. The measured peak gains of the proposed TA are 25.96 dBi and 25.89 dBi at 12.5 GHz and 14.25 GHz. In addition, the measured SLLs of the yoz/xoz planes are -22.4 dB/-22.4 dB and -22.5dB/-22.3 dB at 12.5 GHz and 14.25 GHz, respectively. The proposed TA shows good SLL performances and great application potential in satellite communication systems.

“…For such TAs, independent phase control in each band becomes more challenging due to the polarization requirements. Some dual-band and dual-polarized TAs using two interlaced elements with good performance are proposed in [16][17][18][19]. However, elements of these TAs only have phase tunable ability.…”
