Webb9 aug. 2024 · Designed and fabricated antenna parameters and the SAR value results with and without MM are investigated. The simulated peak SAR values when the antenna with MM is placed on the body model are 0.86, 0.198, and 0.103 W/kg at frequencies of 4 GHz, 7 GHz, and 10 GHz, respectively, for 10 g of tissue. Webb1 apr. 2024 · In the GF-3 SAR antenna system, the cross-polarization radiated pattern F_cross is. In this equation, f _cross mn ( u, ) is the cross-polarization pattern of the antenna subarray, a _cross mn is the crosstalk in the T/R channel, and the value is under −54 dB (equation ( 1 )). Thus, the cross-polarization level is mostly decided by f _cross …
