Design of Stubs in a Comb-Line Leaky-Wave Antenna for Minimizing Gain Variation at Broadside

In this work, the effect of a two-section stub for minimizing gain variation near broadside frequency in a comb-line leaky-wave antenna (LWA) is investigated. Mathematical design conditions for stubs are derived based on the matched input impedance requirement of the unit cell. Based on the derived...
