slot array antenna

Each element of the antenna radiates evenly. Compared with a traditional waveguide slot array antenna, the beam of the antenna is always in the normal phase [Reference Wang, Zhang, He, Chen and Yang 19]. The simulated RHCP and left-hand circularly polarization patterns of 5.5, 5.7, and 5.9 GHz in the E- and H-planes are shown in Fig. 12.
