In order to provide a low profile wire antenna for mobile communication, we have developed a new type of the transmission line type antenna, which we call a Modified Transmission Line Antenna (MTLA). Analysis of a certain type of the modified transmission line antenna has revealed that the input impedance and the gain can be determined independently by appropriately choosing antenna configuration. In this paper, we first explain the fundamental characteristics of the modified transmission line antenna. We then introduce two types of MTLA, i. e. a zigzag MTLA and a double MTLA, for practical application of the MTLA to mobile communication. Their characteristics are also discussed theoretically and experimentally.
