Abstract — An efficient design approach of directional couplers based multiplexers/demultiplexers for optical communication applications, by using an adapted

Photograph of the proposed rectangular patch antenna with its corresponding simulated and measured return loss.. The reflection coefficient characteristics of the proposed

Phase difference between differential output signals, “Type II” excitation..

The discontinuities are represented by the absence of the polyethylene dielectric, and the dielectric constant is set at 1.0006 (air) and the loss tangent is zero. The

The Q value of the proposed QMSIW structure is usually approximately about quarter lower than their conventional SIW since the two opened edges are not perfect magnetic walls

The use of etched FBGs produced in multimode fibers is proposed to overcome the drawbacks associated with sensing high refractive index samples employing fiber

This paper proposed a propagation model for UHF band based on DGF that considers the climatic conditions of the environment, and that leads to deterministic radio propagation

The optimized design is then checked for momentum characteristics for measuring return loss and bandwidth parameters. The return loss characteristics depicted in Fig. 6, reveals
