ABSTRACT: We have developed the triple-band internal antenna for Clamshell type
mobile phone. The frequency range was suitable for European Mobile Phone system:
900MHz and 1800MHz, and USA Mobile Phone system: 1900MHz. To develop the
triple band antenna, we increased the bandwidth at 1800MHz ~ 1900MHz. We concentrated
on optimizing the relation between internal antenna and print circuit
board, and found the best antenna position and design. Also we determined the influence
of varying the LCD panel position on Clamshell type mobile phone.
