Abstract :
A rectangular notch is introduced to expand the impedance bandwidth of a dual-band planar monopole antenna for application in PCS/WLAN systems. The antenna is fed by a CPW line and resembles the shape of the letter ´Y´. Prototypes of the proposed antenna have been constructed and tested. Good measured radiation characteristics of monopole-like patterns, 14.4 and 34.1% bandwidths, and 3 and 4.3 dBi peak antenna gains for the lower (1.95 GHz) and upper (5.45 GHz) bands have been obtained.
