Three-band Modified Transmission Line Antennas for Mobile Communication
In order to respond to recent increases in the number of mobile telephone users, three frequency bands are currently used for mobile telephone systems. We herein propose a three-frequency-band antenna that is useful for mobile telephone base stations. We first developed a two-band antenna called the Double Modified Transmission Line Antenna (DMTLA) that consists of two simplified MTLA of different lengths. By attaching a parasitic element to the DMTLA based on the multi-band technique using parallel transmission line loading, we realize the three-band Double Modified Transmission Line Antenna (3-B DMTLA) for the base station antenna of a mobile telephone system.
