The development of a dual-polarized, lightweight, and flexible antenna for L-band applications is presented. Four single flexible antennas (SFAs) are placed closely to provide dual-polarization and good conformable performance to a cylinder with radius as small as Rc = 40 mm. In planar form, each SFA is a trapezoidal-shaped patch converted into a staircase shape to minimize the antenna size while enabling high bending. For the flat case, the antenna provides a 10-dB impedance bandwidth from 1.15 GHz to 1.31 GHz (13.0%) and a boresight gain of 7.0 dBi at 1.25 GHz. For conformal cases, the antenna maintains the same bandwidth as the flat case. The gain drops from 5.6 dBi to 2.5 dBi when bending the antenna from Rc = 200 mm to 100 mm.
