SIW-Based Uniform Slotted Leaky-Wave Antenna at Ku Band with FR4 Dielectric Material

摘要

In this paper, SIW leaky antenna has been investigated with FR4 substrate. This SIW leaky antenna consists of a series of circular holes with pitch of 0.75 mm along with six cut slots. The width of SIW has been taken as 10.5 mm. Simulations are carried out using tetrahedral mesh using physics controlled mesh with coarser element size. The SIW antenna achieves uniform radiation properties between 15°-75° at 12.25 GHz.
