Cavity Backed Antenna for Microwave Estimation of Grape Bunches in Vineyard
Asia Pacific Microwave Conference-Proceedings(2019)
摘要
The design of a cavity backed dipole antenna is presented in this paper. The antenna is designed for a microwave sensor that is developed to perform automatic estimation of grape bunches in Vineyards. Antenna specifications are derived from the system design and development of the microwave sensor. After a process of antenna type selection, the cavity backed dipole antenna was chosen due to its ability to meet the desired system specifications. To improve the performance of an existing antenna design, we designed a balms that better matches the performance of the antenna. The antenna has been fabricated and measured, achieving an impedance bandwidth of 1.5 to 6.6 GHz.
