<p>PURPOSE: A broadband helical antenna for a portable terminal is provided to improve a narrow band characteristic and receive a DMB signal stably. CONSTITUTION: A broadband helical antenna for a portable terminal includes a helical radiator(200), a conductive pattern(206), a first substrate(202), and a second substrate(204). The conductive pattern is inserted into a spiral structure of the helical radiation. The conductive pattern is electrically connected to the ground. The conductive pattern is a meander form. The helical radiator is electrically connected to the feeder of the portable terminal. The first substrate and the second substrate are made of the dielectric material.</p> |
