Multi band built-in antenna

A planar inverted F antenna, comprising:

• a feed pin through which a current is directed;
• a feed line having a first end coupled to the feed pin and a second end extended from the first end by a predetermined length;
• a coupling pin having one end coupled to said second end of said feed line;
• a radiating patch formed on a surface spaced-apart from said feed line to induce the current directed through the other end of said coupling pin, having a slot having one portion starting from one edge of said radiating patch and another portion extended from the one portion to be disposed in an inside of said radiating patch;
• and
• a shorting member having one end coupled to one end of said radiating patch and the other end coupled to a ground unit.

A planar inverted F antenna in a communication terminal having a ground comprising:

• a feed pin having a feed pad formed on one end thereof to direct a current;
• a feed line having a first end coupled to said feed pin and having a second end extended from said first end by a predetermined length;
• a radiating patch formed on a surface spaced-apart from said feed line to induce the current transmitted through the feed pin;
• and
• a shorting member having one end coupled to said radiating patch, the other end coupled to the feed line, and a coupling pad disposed adjacent to the other end of to be coupled to the ground.

A planar inverted F antenna in a telecommunication terminal having a ground, comprising:

• a feed pin directing a current;
• a first feed line having one end coupled to said feed pin and having a first predetermined length;
• a second feed line having one end coupled to said feed pin, disposed to be parallel to said first feed line;
• a radiating patch formed on a surface spaced-apart from said first and second feed lines by a predetermined distance, having a slot starting one edge end being extended to another edge of the radiating patch to divide said radiating patch into a first patch area coupled to said feed pin and a second patch area coupled to the other end of said second feed line;
• and
• a shorting member having a coupling pad formed on one end of said shorting member to be coupled to said ground, having the other end coupled to said first patch area of said radiating patch, said coupling pad coupled to the other end of said first feed line.
