Biconical Antenna for Mobile Base Station for Post Disaster Area Wireless Communications

This paper proposes an antenna having a frequency ranges of 2G, 3G, 4G and 5G for disaster recovery wireless communications system. The antenna is also functioning for mobile base station (MBS) for both post-disaster and rural areas communications. In Indonesia, 2G-5G mobile communications frequency ranges are operated at 0.8-33 GHz. To cover areas with a radius of 5 km, we propose an Asymmetric Biconical antenna tested by a series of computer simulations, where the material of antenna is brass with a dimension of 261.96 mm × 304.59 mm × 304.59 mm, which is light suitable for MBS. We obtain return loss RL < –10 dB with omni-directional radiation pattern and gain G > 1 dB. We expect that the proposed Asymmetric Biconical antenna contributes to the development of post-disaster area communications as well as contributions for disaster mitigation.
