Abstract
A small, loop-type ground radiation antenna for 2.4-GHz WLAN applications in the complex ground with two vertically attached printed circuit boards (PCBs) was designed. In the presence of a vertical PCB (sub-PCB), the antennas in two different positions, far from and near the sub-PCB, were designed. The current distribution of the complex PCB was stronger near the sub-PCB. Therefore, the coupling between the antenna and the complex PCB was stronger when the antenna was located near the sub-PCB. The antenna close to the sub-PCB obtained more than twice the 3:1 VSWR bandwidth and the efficiency bandwidth than the distant antenna.
期刊介绍：
The Journal of Electromagnetic Engineering and Science (JEES) is an official English-language journal of the Korean Institute of Electromagnetic and Science (KIEES). This journal was launched in 2001 and has been published quarterly since 2003. It is currently registered with the National Research Foundation of Korea and also indexed in Scopus, CrossRef and EBSCO, DOI/Crossref, Google Scholar and Web of Science Core Collection as Emerging Sources Citation Index(ESCI) Journal. The objective of JEES is to publish academic as well as industrial research results and discoveries in electromagnetic engineering and science. The particular scope of the journal includes electromagnetic field theory and its applications: High frequency components, circuits, and systems, Antennas, smart phones, and radars, Electromagnetic wave environments, Relevant industrial developments.
