Abstract
A multi-band antenna (100) including a metal base plate (10) forming an electrical ground plane, and a plurality of metal patches (1 to 3) superimposed on top of the metal base plate. The metal patches are connected in parallel between a signal lead wire (11A) and the metal base plate. The metal patches have respective surface areas which increase with the distance of each metal patch from the metal base plate. The antenna provides as many different resonant frequency values as there are patches.
