This study introduced the smallest radial line slot array (RLSA) antenna to date and examined the impact of cutting on the antenna’s performance to assess the feasibility of this cutting method. The RLSA model and its cut version were designed, simulated, and fabricated to validate the simulations and the method itself. Their performance was then evaluated in terms of gain, reflection coefficient, and bandwidth. The analysis revealed that the method could reduce the antenna size by up to five times while maintaining its gain, which only decreased by approximately 50%. Additionally, this method resulted in a wider bandwidth of around 1 GHz and significantly reduced reflection.
