Minituarized printed L-shaped antenna with parasitic element for ultra-wideband applicatons
2016
This paper presents a new compact printed L-shaped monopole antenna for applications in ultra-wideband (UWB) systems such as home networks and various wireless systems. A miniaturization of the proposed antenna has been accomplished by using a parasatic element, resulting in a design with dimensions 25 mm × 25 mm × 1.6 mm. The antenna is printed on FR4 epoxy and is fed by SMA female connector. The return loss (Su) and voltage standing wave ratio (VSWR) are obtained using both HFSS and CST for different ground plane lengths. The new L-shaped design illustrates good UWB characteristics since it is capable of operating in the range 2–12.31 GHz. Simulation results for Su and VSWR show strong consistency in terms of the bandwidth for UWB operation, under the general criteria of S 11 less than −10 dB and VSWR less than 2:1.
