The case has a base, dimensioned to fit a back of the RF communications device; and a plurality of walls, extending from the base and dimensioned to fit corresponding walls of the RF communications device. The case is configured to cover part of the first portion so as to cause a dielectric parameter adjacent a part of the first portion to be relatively high. The case being further adapted such that a dielectric parameter adjacent the second portion is caused to be relatively low. A method for fitting the case on the RF communications device and method for manufacturing the device is also provided."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Radio frequency properties of a case for a communications device","description":"A case is provided for a portable Radio Frequency (RF) communications device in which the portable RF communications device has an RF antenna arrangement internal to or integrated with an outer housin","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9712203","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
