A magnetic antenna has a first switch unit, a second switch unit, and a concentrated constant circuit which are added to a wiring pattern at the side near to a main antenna, so that a first path and a second path can be selected. Under a predetermined condition, a CPU controls the first switch and the second switch to electrically connect terminal (A1) to terminal (B1) and electrically connect terminal (A2) to terminal (B2), thereby forming the first path; and electrically connect terminal (A1) to terminal (C1) and electrically connect terminal (A2) to terminal (C2), thereby forming the second path connected via the concentrated constant circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Portable wireless device","description":"A mobile wireless device enables effective use of space in a case while reducing degradation of antenna gain and maintaining communication quality even if a plurality of antennas having different freq","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8489109","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.
