Abstract


A dual-band RF sensor antenna that can be used for measuring the strength of GSM 800/900/1800/1900 MHz band radiations from nearby base station antennas or handsets is presented in this work. The dual-resonance was achieved by cutting an L-shaped slot in a spatula-shaped patch. Measured 10 dB return loss bandwidth is from 740 to 960 MHz in lower band and 1650 to 1950 MHz in upper band. The antenna factors are between 26-33.2 dB/m.
