N2 - This paper elaborates on a design methodology for a wide-band internal beam pointing angle fixed leaky-wave antenna. A leaky-wave antenna design method based on complementary reactance loading is proposed. The loading of supplementary reactance makes it easier to match the antenna to the feed transmission line and achieve broadband radiation. In order to obtain better antenna performance, the leaky-wave antenna with larger slot size is selected. Therefore, a geometric optimization method for large-scale leaky-wave antennas is proposed, which can effectively reduce the optimization space range. The combination of geometric optimization and particle swarm optimization can effectively shorten the optimization time and realize efficient antenna design. Finally, simulation results indicate that in the context of single-beam pointing, this method can ensure beam angle fixation within the frequency range of 5.5 GHz to 6 GHz. For dual-beam pointing scenarios, the method can achieve beam angle fixation within the frequency range of 5.6 GHz to 5.9 GHz.
