A multiple frequency band antenna is capable of operating in at least three distinct preselected frequency bands. The antenna includes a planar inverted F antenna (PIFA) extending horizontally, a ground leg and feed leg integrally formed therewith and extending at an angle to the PIFA. The PIFA includes a slot formed therein that separates the PIFA into an inner base portion and outer branch portion, the outer branch portion extending from one end of the base portion extending from one end of the base portion and at least partially around a perimeter of the base portion. The antenna includes a horizontal conductive element extending from the ground leg and interposed between the PIFA and associated ground plane, and the horizontal element defines an additional, or third radiating element of the antenna, which broadens the bandwidth of the antenna. |
