Abstract :
A triangular-ring slot antenna fed by coplanar waveguide feed line with a protruded tuning stub and a back-patch at the bottom of the substrate for miniaturization has been demonstrated. A design example has been successfully implemented, Experimental results show that the resonant frequency can be significantly reduced, as compared with the CPW-fed conventional ring-slot antennas.
