摘要
Abstract
A side-fed rectangular microstrip patch antenna is designed for humidity sensing.Its 2.4 GHz operating frequency and structural dimensions are determined by HFSS simulation design.The microstrip patch antenna prepared using a self-built direct-ink-write printing system is investigated for humidity sensing,and the PDDA moisture-sensitive material is coated on the sensitive area of the radiating patch for enhancing the moisture-sensitive characteristics.The results show that PDDA plays a key moisture-sensitive role,and the microwave antenna obtained by direct-ink-write printing is able to act as a high humidity alarm and humidity sensing in the medium-high humidity range of 50%RH～90%RH.The sensitivity is 250 kHz/%RH and linearity is 0.95.关键词
