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 mm2) 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). |
