Variety <strong>and</strong> principle of basic antenna dipole antenna<br />
17<br />
λ/4 λ/4<br />
Ground part of monopole antenna<br />
changes to linear λ/4 in length<br />
Unlike monopole antenna, characteristics is<br />
stable because of independent structure.<br />
It is used as a st<strong>and</strong>ard reference antenna<br />
due to its certain characteristics.<br />
advantage→stable characteristics.<br />
can be use for st<strong>and</strong>ard antenna.<br />
disadvantage→total length becomesλ/2,<br />
so it gets big.<br />
difficult to miniaturize.<br />
