SMALL ULTRA-WIDEBAND ARRAY ANTENNA BASED ON AN ULTRA-WIDEBAND POWER DISTRIBUTER OF A ZEROTH RESONANCE META-MATERIAL STRUCTURE CAPABLE OF INCREASING ANTENNA EFFICIENCY USING A FLAT ANTENNA STRUCTURE

摘要

PURPOSE: A small ultra-wideband array antenna based on an ultra-wideband power distributer of a zeroth resonance meta-material structure is provided to utilize a stub and an inter-digital structure in a micro strip band pass filter for forming a zeroth resonance band pass filter.;CONSTITUTION: A short-circuit pin connected to ground is formed by replacing a line length of a power distributer. A wave filter comprises two micro strip stubs which form an inter-digital structure. The power distributer is operated in an ultra wideband without a complex multi-layered structure. The power distributer is attached to two component radiators of an array antenna for securing an antenna band and an impedance matching operation.;COPYRIGHT KIPO 2012
