Design of Tilted E-Shaped Monopole Antenna for Vehicular Communication

In the field of wireless communication systems, there has been a large and rapid increase recently. Every piece of wireless technology in today's world includes Wi-Fi. The transportation sector is frequently afflicted by issues such as traffic congestion and accidents. Despite this, in terms of vehicle collaboration, it has been evolving in recent years. The goal in this scenario is to use a compliant antenna system to provide good data connectivity. This movement's main goal is to improve road safety by anticipating potentially dangerous situations. Small and compact antennas are used in wireless applications. The driving signal from the transmitter is applied between the ground plane and lower end of the monopole, or the output signal from the receiver is taken in case of receiving antennas. One end of the monopole is connected to the ground plane and the lower end of monopole is to the antenna feed line, which is usually the Earth. This research focuses on a small Microstrip antenna for use in C-band applications. The antenna is a monopole tilted E-shaped patch antenna with rectangular slots and a deficient ground structure. The frequency range where the return loss (RL) is greater than −10 dB is referred to as the antenna bandwidth (−10dB corresponds to VSWR of 1.2). The simulated S11 (return loss) for the obtained resonant frequency range of 5. 9 to 7.2 GHz is −18.816dB, and the VSWR is less than 2. This antenna simulation yields a directivity of 6.13 dB and a gain of 6. 04 dB both of which are acceptable.
