Abstract
A low profile, rectangular E-shaped microstrip patch antenna is designed and proposed for radio-frequency identification (RFID) based intelligent transportation system (ITS) in this paper. The proposed antenna design aims to achieve high gain and low return loss at 0.96 GHz as it is suitable for ultra-high frequency (UHF) RFID tags. The proposed antenna composed of a radiating patch on one side of the dielectric substrate and the ground plane on the other side, copper is used to produce the main radiator. The simulation of the proposed antenna is performed employing the high-frequency structure simulator (HFSS). The dielectric substrate used for the suggested antenna is an FR4 substrate with dielectric constant of 4.3 and height 1.5 mm. The performance of the proposed antenna is measured in terms of gain, return loss, voltage standing wave ratio (VSWR), radiation pattern and the bandwidth. The antenna gain and the return loss of the suggested antenna at 0.96 GHz are 7.3 dB and -12.43 dB, respectively.

Summary
Public transportation systems are an essential element of human lives. It is a known fact that every year thousands of human lives are lost in the road accidents. Road accidents can be mitigated by controlling the transportation systems intelligently using the technology, as every year millions of new vehicles hit the roads. In 2016, 77.31 million cars have been sold and this number has increased in 2017 by 1.28 million and counting [1]. It is getting difficult to handle the transportation traffic using manual management systems. Thanks to the intelligent transportation systems (ITS), which proffer effectual solution for many transportation troubles as contrasted to the traditional solutions [2]
