Antenna Design for Multi-generation 2G-5G for Rural Area Wireless Communications

The development of telecommunication generation is faster compared to the development of infrastructure in rural areas. This paper proposes an antenna having capability of multi-generation (MG) communications of 2G, 3G, 4G and 5G for rural area wireless communications. The antenna is also functioning for mobile cognitive radio base station (MCRBS) for post-disaster communications in either rural or urban areas. In this paper, the antenna is designed to work at the operating frequencies of 2G–5G in Indonesia, which are expected in between 0.8 GHz to 6 GHz. To cover any areas with radius of 5 km, we propose a Vivaldi antenna, called as MG-Vivaldi antenna, tested by a series of computer simulations, which is realized using aluminum with dimension of 50 cm × 100 cm. We obtain an MG-Vivaldi antenna having return loss RL ≤ −10 dB with gain G > 8 dB. We expect that the proposed MG-Vivaldi antenna contributes to the development of rural area communications as well as contributions for disaster mitigations.
