This paper presents a miniaturized spurline microstrip RF resonator to moisture loaded organic material, soybean seeds using overlay technique. The permittivity has calculated from the frequency response of the moisturized seeds. The RF microstrip spuriine resonator with high Q is so sensitivity to the organic material that helps to sense the moisture content seeds and it is simulated and observed the frequency response at 10 GHz with insertion loss of 40 dB. The designed RF resonator has high quality factory (Q) which is good for using it as a sensor. The resonator can also be characterized using vector network analyzer before and after loading the soybean on the sensitive area of the resonator and we can have frequency difference due to difference in dielectric constant. Random orientations can be done while characterizing the spurline resonator.
