Abstract :
A novel microstrip patch antenna with a Koch prefractal edge and a U-shaped slot is proposed for multi-standard use in GSM1800, UMTS, and HiperLAN2. Making use of an inverted-F antenna (PIFA) structure, an interesting size reduction is achieved. The multi-band behavior has been obtained by broadening the lower frequency resonance of the fractal patch to cover GSM1800 and UMTS, and inserting a U-slot dimensioned for the HiperLAN2 band. The effect of the small ground plane has been taken into account. Experimental results have validated the design procedure and confirm the fulfillment of the requirements for multistandard mobile terminal applications.
