Studies on Permittivity and Moisture Content of Sunflower Seeds Using Microstrip Equilateral Triangle Patch Antenna
نویسندگان
چکیده
This paper reports the Ku band (1318GHz) response of thick film equilateral triangle microstrip patch antenna to moisture laden sunflower (Helianthus Annuus) seeds using overlay technique. From the frequency response the moisture dependent microwave permittivity has been reported. The thick film patch antenna is sensitive even to ~ 4.25% moisture content in the overlay material. The actual moisture content and predicted moisture content match indicating that this technique can be used for even moisture sensing at low moisture levels.

متن کاملModified Rectangular Patch Antenna Loaded With Multiple C Slots for Multiple Applications
A new multiple C-slotted microstrip patch antenna is proposed in the present study. A patch antenna is a wide-beam narrowband antenna. The microstrip patch antenna consists of a very thin metallic strip (patch) placed a small fraction of a wavelength above a ground plane. The patch can be designed in any possible shape and normally made of conducting materials such as copper or gold. This study...
