A novel multi-band sensing antenna for electric field measurement with multi-layer PCB layout

Monitoring electromagnetic radiation from mobile communication base station is an important guarantee to ensure the quality of the mobile communication services and also a necessary means to ensure the safety of electromagnetic environment. Focusing on the requirements of sensing antenna for electric field measurement, the core components of monitoring equipment, this thesis has designed a novel dielectric embedded multi-band microstrip dipole antenna; the series fed antenna is embedded in the dielectric substrate to reduce the antenna size effectively by the multi-layer PCB layout technology. The antenna is designed by simulation and optimization and the antenna is manufactured to measure the parameters. The results show that the working band basicly covers 2G, 3G, and 4G spectrums which ranges between 0.850 GHz-0.950 GHz and between 1.670 GHz-2.740 GHz, the radiation pattern has good omnidirectionality and the size is 72.0 mm×48.0 mm×6.0 mm. It can meet the requirements of specificity, multi-band, sensitivity, isotropy and portability of sensing antenna for measuring electromagnetic radiation of mobile communication base station. The sensing antenna for electric field measurement can be used to measure the electric field intensity around the base station.
