“…However, the conformal antenna was located inside the carrier, which offset the ground profile characteristics of the patch antenna and occupied a large space. T P S Kumar Kusumanchi et al [ 15 ] produced a novel approach for the simulation of hexagonal conformal array (HCA) antenna design. [ 16 ] proposed an extremely ultrathin 2-D isotropic flexible meta-surface energy harvester (MEH) using a multi-polarized patch frequency selective surface.…”

Antenna beam deflection, along with miniaturization and wideband of the antenna is in demand for practical applications. In this paper, a cylindrical conformal array antenna with a small-tilt forward beam was designed. The microstrip antenna unit was loaded with the artificial electromagnetic structure, which reduced the size of the antenna unit. As a result, the center spacing of the array elements can be shortened with the same array element spacing. The beam deflection angle can be increased in this way without increasing the coupling effect between the parts. Changing the number of line array elements and the number of line arrays can regulate the beam width of E-field and H-field, respectively. The bandwidth of the antenna can be significantly extended by slotting the ground plane. This work implemented a cylindrical conformal array of the antenna’s forward beam with a small dip angle using a cylindrical carrier as an example. The measurement results showed that the angle between the main beam and the carrier axis of the conformal antenna was less than 30°, the bandwidth was more than 30%, and the antenna volume decreased by 40.4%.
