摘要
A new multi-functional vehicle antenna, consisting of LNA-integrated non-uniform helical antenna for both FM and terrestrial digital multimedia broadcasting (TDMB) operation, and a monopole antenna for the PCS operation is proposed. The proposed architecture combines the three antennas in such a way as to maximum the reuse of the antenna structure and, thereby, reduces the overall antenna size. To realize a single-port excitation of three different band antennas, the PCS antenna and FM antenna is simultaneously excited with the help of steel stud while the TDMB antenna is magnetically coupled from a portion of the FM antenna body.
