Abstract
A new method of shared antennas aperture was presented. In the weak radiation area of low-frequency single-cone antenna integrated high-frequency microstrip antenna array, two antennas with different frequency bands and polarizations could share an antenna aperture. The volume and weight of proposed antenna are same as the original low-frequency mono-cone antenna. Two feeding ports of the antenna were integrated on the ground of the original mono-cone antenna. Meanwhile, using software HFSS analyzed the antenna. The results show that the return loss is less than –10 dB in frequency bands 0.7–1.3 GHz and 4.1–4.2 GHz, the isolation between two ports is more than 31 dB, the antenna radiation pattern is omni directional in 0.7–1.3 GHz and directive in 4.1–4.2 GHz (gain is 11 dBi at 4.15 GHz), the simulation results verify the feasibility of the shared aperture method.关键词
