Abstract

In this paper, folded PIFA is proposed by using folding the end point of PIFA for the automobile DMB antenna. By turning down the end point on the opposite side of shortstrip, resonance frequency is presented at not $\lambda$/4 but $\lambda$/10. So the folded PIFA has size reduction effect approximately 60 % as compared to the conventional PIFA. Also by using the parasitic patch, folded PIFA provides wide band performance. As a result, the designed antenna can be in the application of Digital Multimedia Broadcasting(180 $\sim$ 210 MHz) antenna for the automobile.
