Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
116 words
An antenna connector comprising: a magnetic core which is a combination of an E-shaped core and an I shaped core; a signal line which pierces through holes of the magnetic core and is wound around the magnetic core at least once; a case which contains the magnetic core and the signal line inside; a first terminal which is disposed at one end of the signal line to electrically connect the signal line with a high-frequency appliance, the first terminal being fitted on the case; and a second terminal which is disposed at the other end of the signal line to electrically connect the signal line with an antenna, the second terminal being fitted on the case.
