资源简介：
This design presents a novel tightly coupled dipole array (TCDA) with a bandwidth of 26.1:1 (VSWR < 3) in the 0.20-5.22 GHz band. By adding a new dual-stopband resistive frequency selective surface (RFSS) between the TCA and the floor, the short-circuit points formed by the floor at the frequency points corresponding to λ = 2h and h (h is the height from the antenna to the floor) are both eliminated. By placing a specific wide-angle impedance matching (WAIM) above the antenna, the impedance bandwidth and beam scanning ability of the new dipole antenna are further improved under the premise of ensuring lightweight and a low profile of 0.05 λlow. Simulation and experimental results show that the designed TCA has extremely wide bandwidth, good directivity and wide-angle scanning characteristics. Compared with previous designs, it greatly extends the bandwidth and improves the gain.
