Abstract:A high-efficiency mobile phone antenna covering GSM band (880-960 MHz), DCS1800, PCS1900, UMTS, LTE2300 and LTE2500 band (1710-2690 MHz) with a narrow ground clearance of 2 mm is proposed considering the effect of head and hand of human. Such antenna for metal-rimmed smartphone applications is to address the performance deterioration caused by the users. It is found that a high efficiency can be obtained by making the main beam of the antenna not point to the head and hand because less energy is absorbed by hu… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
