Abstract :
An inverted LFFL card antenna (InvLFFL) is designed as a quadband antenna, where target frequency bands are 1.7 GHz, 2.45 GHz, 3.5 GHz, and 5.2 GHz bands. The InvLFFL is composed of a modified inverted L element, two inverted F elements, and a parasitic inverted L element. The design is performed based on one-quarter wavelength resonance at each band. The InvLFFL has a 4.6% bandwidth around 1.7 GHz, a 2.4% bandwidth around 2.45 GHz, a 2.0% bandwidth around 3.5 GHz, and a 3.9% bandwidth around 5.2 GHz for a VSWR = 2 criterion.
