Investigators at Samsung Electronics Discuss Findings in Antennas and Propagation (Radiation Efficiency-Improvement Using a Via-Less, Planar ZOR Antenna for Wireless ECG Sensors on a Lossy Medium)

By a News Reporter-Staff News Editor at Electronics Newsweekly -- Investigators publish new report on Antennas and Propagation. According to news reporting originating from Suwon, South Korea, by VerticalNews correspondents, research stated, "The critical issues involving severe radiation efficiency degradations during wireless electrocardiogram (ECG) health monitoring sessions are addressed by devising a monolithic zeroth-order resonance (ZOR) antenna. The presented antenna consists of a composite right/left-handed (CRLH) structure that is realized on a single, planar surface of the flexible printed circuit board (PCB) without the use of any via-holes."

Our news editors obtained a quote from the research from Samsung Electronics, "This significantly alleviates the complexity and fabrication cost involved with vertically polarized antennas with monopole-like radiation patterns, which are important factors in consumer electronics. Moreover, this letter investigates the practical issues associated with effects of the in-house designed ECG device circuit board, feeding mechanism with the RFIC, as well as the polycarbonate chassis. The finalized antenna is less than in total horizontal dimension with zero height profile."

According to the news editors, the research concluded: "Measurement confirms the presented antenna features more than 30% radiation efficiency across 80 MHz bandwidth when completely integrated within the ECG sensor device and placed on the human body phantom."
