Abstract


A compact antenna with a coupler is laid down using Substrate Integrated Waveguide (SIW) technique, which operate at X-band of frequencies. The SIW coupler has a SIW section which includes inserted metallic post. These metallic post acts as an inductive-post. SIW innovation is the most talented contender for the achievement of millimetre wave (mm-wave) coordinated circuits. Supported on planar dielectric substrate with bottom and top metal layers implanted with coated metal holes, it offers a compact, low cost, less loss and flexibility. The SIW has dynamic as well as passive components emanating area on the similar substrate. SIW technology has some attractive advantages, such as compact size, low loss, easy construction, low weight, high integration and is suited for all microwave and millimetre-wave works. The utilization of SIW technology encourages us to trim down return loss when weighed against other printed advances. The manufacturing process can simply be finished by means of normal Printed Circuit Board (PCB) process, where this present procedure’s cost will be shortened when assessed with conventional waveguides. The SIW coupler more frequently utilized as a part of radar, point-to-point radio and satellite. Simulations results come about demonstrate the coupler’s execution having low insertion loss, low return loss, and expansive operational data transmission and enclose fine seclusion.
