<p>A dual resonance frequency inverted F antenna (PIFA) comprising an element defined by a first conductive layer (4), a ground layer (3) defined by a second conductive layer, a first open end slot (6) and a second close end slot (7), which second close end slot is connected to said first open end slot, a feeding connection (1) and a ground connection (2), said connections arranged in the vicinity of the closed end of said first open end slot (6), means for tuning the resonance frequencies separately for each band in the form of a first (31) and a second resonance part (32) provided in the element at each side of a first open end slot (6) and means for tuning resonance frequency for both bands thogether in the form of said first open end slot (6) and said second close end slot (7).</p> |
