A compact pentaband planar inverted-F antenna (PIFA) suitable for handheld terminals is presented. This antenna is made of capacitively loaded shorted patches, a slot, and an efficient antennachassis combination to achieve multiband and wideband performances Figure 3 Measured radiation pattern in three orthogonal x-y, x-z, y-z planes at 4, 6, and 8 GHz to operate in the 850 MHz, 900 MHz, 1800 MHz, 1900 MHz, and UMTS bands. Matching, radiation properties, and efficiency show that this antenna is suitable for these mobile communication standards.
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.
