<p>An antenna for mobile communications including first and second bodies of conductor, each having races whose length and diameter are designed in consideration of the antenna's frequency and gain characteristics; a spacer of a non-conductor interposed between the first and second bodies so as to keep a given space between the respective races of the first and second bodies according to the frequency and gain characteristics; an inner core fixing two bodies to each other with screwed parts respectively inserted into screwed grooves each passing through the races' bottom, and electrically connecting the first body to the second body; and a coupling part for feeder connection of a transmitting/receiving circuit for a mobile communications terminal. This inventive antenna is installed in a case of a cellular phone not to protrude to the outside of the case. In addition, this antenna can be mounted on an automotive vehicle by using an antenna base.</p> |
