[9] H. Sabri and Z. Atlasbaf, “Two Novel Compact Triple- Band Microstrip Annular-Ring Slot Antenna For PCS-1900and WLAN Applications”, Progress In A compact rhombus-shaped slot antenna fed by microstrip ... In this paper, a novel design and experimental study of microstrip-line-fed rhombus-shaped slot antenna is presented. The proposed antenna shows an ultra-wide band (UWB) operation with good impedance matching by choosing appropriate rhombus-shaped slot and feeding structure.
