Miniarutized and lightweight automotive antenna design for vehicle to vehicle communication

In this paper, automotive antenna design for vehicle to vehicle communication is proposed. Antenna design is based on elliptical geometry by utilizing the self-similarity of the fractal concepts. The initiator is an elliptical shape based vertical to horizontal ratio of about 3∶1. The proposed antenna is a combination of two reproduced elliptical shape placed at +/− 30 degrees to the central point of the initiator. Antenna is miniaturized (42 × 34 mm
²
) and lightweight with efficient characteristics. Simulation results show that the presented antenna has a reflection coefficient characteristic better than −17.5 dB, 70% radiation efficiency, 4–6dBi antenna gain and omni-directional radiation pattern properties over the 75 MHz of 802.11p standard (5.85 – 5.925 GHz).
