In this paper, we propose for the first time a novel feed approach to tightly coupled dipole array (TCDA). Firstly, compact zigzagging microstrip feedlines are utilized as baluns our elements obtain wideband impedance-matching characteristics. Secondly, is designed on ultrathin substrates aiming at obtaining ultra-tight coupling between arms of two neighboring elements. Some irreplaceable paras...

This article presents the design, modeling, and fabrication of a printed log-periodic biconical dipole array antenna (PLPBDA) for electromagnetic compatibility (EMC) measurements. The proposed structure used bow tie-shaped dipoles instead typical to achieve size reduction 50% bandwidth enhancement 170% with help PCB technology. Furthermore, balanced feeding method modifications in dimensions we...
