摘要

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).

The Radiation Characteristics of 3.43:1 Bandwidth Dipole Antenna with Radar Absorbing Material

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).
