A novel wideband compact circularly‐polarized metasurface antenna for modern vehicular communication systems

“…Consequently, there is a growing need for antennas with wideband features. 14,15 For example, Dedicated Short-Range Communication (DSRC, specified by IEEE 802.11p) operating in 5-GHz band, plays an important role in vehicular communications, enabling vehicle-to-vehicle (V2V), vehicle-to-roadside (V2R), and vehicle-to-pedestrian (V2P) direct information exchange. Another example is the electronic toll collection (ETC) system, which commonly uses 915 MHz, 2.45 GHz, and 5.8 GHz frequency bands.…”

“…Furthermore, as wireless communications continue to advance, 12,13 the electromagnetic environment becomes increasingly complex, and channel interference becomes more severe. Consequently, there is a growing need for antennas with wideband features 14,15 . For example, Dedicated Short‐Range Communication (DSRC, specified by IEEE 802.11p) operating in 5‐GHz band, plays an important role in vehicular communications, enabling vehicle‐to‐vehicle (V2V), vehicle‐to‐roadside (V2R), and vehicle‐to‐pedestrian (V2P) direct information exchange.…”
