Internal antenna of wireless communication terminal
First Claim
1. An internal antenna of a wireless communication terminal comprising:
- a first folded radiation plane having an end to which an input port is connected;
a second folded radiation plane having an end to which a shorting pin is connected;
a transmission line for connecting the first radiation plane to the second radiation plane; and
a junction branched from the transmission line.

Abstract
An internal antenna of a wireless communication terminal, in which internal style folded monopole antenna is installed, is provided. The internal antenna of a wireless communication terminal includes a folded monopole antenna. The folded monopole antenna includes two folded radiation planes having a quarter wavelength, and reactances loaded to predetermined positions of the two radiation planes. Therefore, a space for installing the antenna in the terminal is minimized, and due to the no directional characteristics, the internal antenna can be applied to a wireless communication system of dual bandwidths.
