Design of the 1.7 GHz LTE RF-EMF cell exposure system. (A) A schematic diagram of the radial transmission line (RTL) exposure system. (B) Cross-sectional view of the RTL exposure chamber. (C) Return loss characteristics of the RTL exposure chamber. (D) Antenna and the measurement points in each culture plate. (E) Temperature and linear fitting for the center point at the LTE 1.7 GHz frequency. Temperature was measured without circulating water during RF exposure.
