A Design of Flexible Materials Microstrip Antenna

A microstrip antenna based on flexible materials is designed. It adopts a flexible dielectric substrate, a radiating patch, a microstrip feeding method and a floor slot structure. Its size is 24mm×14mm×0.038mm, which conforms to the trend of antenna miniaturization. The electromagnetic simulation software Ansoft HFSS is used to simulate and optimize the antenna in the planar state and the conformal state. The results show that it can work in the 5G operation frequency bands of 2.49-2.69GHz and 5.15-5.85GHz in the planar state and the conformal state, which has the characteristic of omnidirectional radiation and its maximum gain is 4.4dBi.
