PCB antennas present some excellent characteristics for low power communications, typically used in wireless sensor networks, such as low profile, low weight, compactness, durability, and versatility to suit several applications. However, these antennas tend to be chosen by the module manufacturer rather than the chips, and due to design constraints, it can lead to suboptimal placement within the communication module. To address this issue, this article presents a technique to evaluate the positioning and orientation of these antennas to aid network designers in properly deploying PCB antennas integrated into communication modules.
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.
