Design investigation of a leaky-wave antenna aimed to acquire continuous beam scanning from the backfire direction to the endfire direction is presented on a Double-Sided Parallel-Strip Line (DSPSL) structure. The unit cell comprises a DSPSL structure and a pair of inverted open-ended stubs attached to the top and bottom strips, respectively. The loaded stubs act as a dipole and provide omnidirectional radiation performance, contributing to the full-space beam scanning potential of the leaky-wave antenna. To eliminate the open-stop band effect, two pairs of series slots are etched on the transmission line to meet the frequency balanced condition and match the Bloch impedance. Experiments of the designed prototype were consistent with the simulation, revealing that as the frequency varies from 7.6 GHz to 14.0 GHz, the proposed leaky-wave antenna radiates beams from the backfire direction through the broadside to the endfire direction.
