Measurement data for the antenna

This paper presents a multi-wide band monopole antenna for automotive application in the Long-Term Evolution (LTE) and 5G systems that covers the frequency range from 617MHz to 5GHz with reasonable rejection on the L1/L2/L5 GNSS bands. The antenna is suitable for placement on a car roof within a shark-fin radome due to its physical dimensions and performance. The antenna is simulated using software and then fabricated and measured on a one-meter ground plane and on a vehicle roof. The measurement results of the fabricated prototype are presented and plotted in terms of VSWR, radiation patterns, antenna efficiency, and linear average gain (LAG). The proposed antenna shows very good properties that makes it suitable for the automotive industry.
