## Abstract A simplified design procedure for dualโ and tripleโlayered RibletโSaad directional couplers in substrateโintegrated waveguide (SIW) technology is presented. Emphasis is placed on a design that considers ease of fabrication and includes interface ports such as microstripโtoโSIW transitio
In this paper, a new approach to optimally design a phase shifter consisting of a periodic array of ferroelectric-based tunable planar interdigital capacitors (IDCs) is presented. Spiral slots in the proposed configuration reduces the overall size and improves the performance by 30%.
