WIDE-BAND MICROSTRIP PATCH ANTENNA WITH DEFECTED GROUND PLANE

摘要

PURPOSE: wideband microband fishplate bar antenna is set to prevent from increasing volume or weight antenna by improving the antenna of bandwidth characteristic without additional equipment using defective earth plate. ;CONSTITUTION: the first dielectric base plate is towards the second dielectric base plate (12). The second dielectric base plate is formed on the downside of earth plate (31). Earth plate has the square spread bandwidth of a defect grounding structure (32). Air layer (21) is formed between the first and second dielectric substrates, to reduce the antenna. ;The 2011 of copyright KIPO submissions
