Patent Number: 6,806,834

Title: Multi band built-in antenna

Abstract: A planar inverted F antenna (PIFA) includes a feed pin supplying a current, a feed line having one end electrically coupled to one end of the feed pin and having a predetermined resonance length, a coupling pin coupled to the other end of the feed line, and a radiating patch formed on a plane spaced-apart from the feed line by a predetermined distance to induce the current supplied through the other end of the coupling pin, and a slot having one end starting at a portion of an edge and the other end disposed in an inside portion of the radiating patch, and a shorting pin having one end coupled to the radiating patch and the other end coupled to a ground. The PIFA becomes smaller by using an electrical resonance length of the feed line, a shape of the feed line, and the open stub and the matching pad, improves the flexibility of the antenna design, and obtains a wider frequency band.
