<p>PURPOSE: An antenna is provided to control simply resonant frequency by using antenna radiation elements for forming an inverted F antenna and an inverted L antenna. CONSTITUTION: An antenna is formed with a two-layered structure of the first antenna radiation element(1) and the second antenna radiation element(3). The first antenna radiation element(1) is formed with an inverted F antenna. The second antenna radiation element(3) is formed with an inverted L antenna. The second antenna radiation element(3) is formed at a ground plate(2) of the first antenna radiation element(1). A feeder terminal(4) is connected to the first and the second antenna radiation elements(1,3). One end of the first antenna radiation element(1) is connected to the ground plate(2) through a ground terminal(5).</p> |
