Abstract:

 The dielectric properties of the leaves due to presence of water in varying quantities can be detected using microwave methods. Microstrip L – section λ/2 rejection filter can be used to investigate the effect of leaf moisture on their response. The investigations are reported in Ku band. An approximate estimate of the effective dielectric constant of the leaf has been made using overlay technique. It is felt that thin film λ/2 rejection filter can be used to monitor the moisture status of leafy vegetation in Ku band frequency range.

Keywords:

λ/2 rejection filter, overlay technique, thin film, leaf moisture, Ku band, effective dielectric constant.
