measurement data for Wide Bandwidth Low Profile PIFA Antenna for Vehicular Sub-6GHz 5G and V2X Wireless Systems

This paper introduces a low profile wideband Planar Inverted-F antenna (PIFA) for vehicular applications in the 5G systems (below 6GHz) and Vehicle-to-Everything (V2X) communications. The antenna covers a wide range of bandwidth that operates from 617MHz to 6GHz while having an acceptable filtering on the GNSS bands. This design’s physical dimensions and electrical performance makes it suitable for low profile wireless applications in the automotive field. Measurement data on Ground plane (GND) and on vehicle are presented from properly cut metal sheet prototype along with simulated results of the model design. Simulation and measurement results are discussed in terms of return loss, surface current distribution, radiation patterns, antenna efficiency, and linear average gain (LAG).
