Abstract :
A compact antenna with an improved gain is proposed for ultra-wideband (UWB) systems. A semicircular slot antenna fed by a CPW to CPW transition at the edges of semicircles is employed as the base UWB radiator and a short, two-plate, TEM-like horn is mounted on the surface to enhance the gain over the entire UWB bandwidth. Theoretical and experimental investigations have been conducted to verify the effectiveness of a two-plate short horn as a means for gain enhancement. Experimental results indicate a wide impedance bandwidth from 2.86 to 11.6 GHz and an approximately 3 dB gain enhancement across the band.
