Circular Ring-Shaped Patch Antenna for Automotive Communication and DSRC Applications

The proposed work presents a compact antenna which is used for automotive applications. The proposed antenna is designed using polyamide substrate which is having dielectric constant of 2.9 and having dimensions of 25 × 30 × 0.1 mm3. The proposed antenna is having Circular radiating patch which later modified to get desired band of frequencies. The proposed antenna is focused to work at 4.25-6.8 GHz (WLAN, DSRC, WAVE, V2X) bands for vehicular communications. The other antenna parameters such as gain (which varied between 3.2-4.1 at working bands) is analyzed for antenna. The antenna is placed on vehicular environment scenario and checked its reliability when it is placed on different vehicular positions. The simulated obtained results tell the antenna is suitable to use for vehicular communication and for dedicated short range communications.
