Shared aperture multi-service antenna design for automotive communications

摘要

This invention shared aperture multi-service antenna design for automotive communication relates to a novel multiservice antenna comprising of modified Planar Inverted F Antenna (PIFA) and a "Y" shaped monopole sharing a common aperture. The modified PIFA is designed for triple band operation at 1.8 GHz, 2.4 GHz and 3.5 GHz, which suitable for DCS1800, IEEE 802.1 lb/g/n standards and Worldwide Interoperability for Microwave Access (WiMAX) respectively. These frequency bands are also of interest in 4G Long Term Evolution (LTE) communication systems. The "Y" shaped monopole is designed to operate at 5.85 GHz for Electronic Toll, Vehicle to Vehicle (V2V) and Vehicle to Infrastructure (V2I) communications. The proposed antenna can be easily integrated with the associated PCB electronics resulting in low cost production of antennas for modern automotive wireless communication requirements.
