Abstract
In this paper it is shown that the use of radar absorbing material (RAM) allows to expand the working frequency band of the antenna by 330 MHz (6.3%). The antenna with RAM had a working frequency band by the level of $\mathbf{VSWR}\leq 3$ in the frequency range 2.29-7.85 GHz (3.43:1 bandwidth). The antenna without RAM had a working frequency band by level of $\mathbf{VSWR}\leq 3$ in the frequency range 2.30-7.53 GHz. The use of RAM allowed to increase the realized gain at the frequency of 7.85 GHz by 1.1 dB (from −11.2 to −10.2 dB).
本文表明，雷达吸波材料(RAM)的使用可以使天线的工作频带扩大330 MHz (6.3 MHz)%). The antenna with RAM had a working frequency band by the level of $\mathbf{VSWR}\leq 3$ in the frequency range 2.29-7.85 GHz (3.43:1 bandwidth). The antenna without RAM had a working frequency band by level of $\mathbf{VSWR}\leq 3$ in the frequency range 2.30-7.53 GHz. The use of RAM allowed to increase the realized gain at the frequency of 7.85 GHz by 1.1 dB (from −11.2 to −10.2 dB).
