Abstract
In the present paper, we minimize the losses & to reduce the size & cost new technology known as planar transmission line technology has been developed with the advent of microwave integrated circuits (MIC’s). When two microstriplines are placed together in close proximity, natural coupling exit between them. Such coupling exits in stripline and slot lines also which are open in transverse direction. The coupling and directivity are the function of the width of the microstripline and the separation between the two striplines. Due to power flow through the structure energy dissipation occurs which results in thermal effect. This affects the coupling and directivity which is the aim of the present study.
