Title
Performance analysis of advanced bus information system using LTE antenna.
Abstract
Improving traffics flow represents a critical situation due to recent increases in traffic volume, despite continuous construction and extension of highways and national roads. Therefore, an effective traffic control and management method using advanced technologies is required in order to relieve traffic congestion. An intelligent transportation system (ITS) applies advanced traffic, electronics, communication, and control technologies to various elements of transportation systems including roads, vehicles, and in order to collect, manage, and provide real-time traffic information. This can maximize the effectiveness of transportation facilities, implement increases in traffic convenience and safety, and reduce energy. A bus information system is an advanced transportation system that provides information, which is collected and processed in real-time, on operating city buses to users through advanced transportation networks. It provides bus operation management services, including route information bus location information to drivers. To ensure the accuracy of the bus information system, the structure of the receivers must be complex, as different base stations must account for buses in each region. This results in difficulty in obtaining real-time information due to the unsmooth hand-over between the base station and bus. In this paper, we carry out a performance analysis of an LTE antenna for use in an advanced bus information system. In the proposed design antenna, a particle swarm optimization method based on HFSS is used to design an LTE antenna. The aim of this paper is to design and fabricate a CPW-fed rectangular LTE antenna as well as study the effects of antenna length, width, substrate parameters relative dielectric constant, and substrate thickness on radiation parameters of band width. When the antenna was designed, a dual-band, dual-polarized antenna was used to secure bandwidth and improve performance.
