Patent ID: 7768468

Claim:
An arrangement for increasing bandwidth comprising: a first loop antenna having a connector adapted to directly conductively couple the first loop antenna to a transmitter or receiver, the first loop antenna having a first resonant frequency, with a first frequency of peak response, and a first bandwidth distributed around said first resonant frequency; a second loop antenna lacking a direct conductive connection to said transmitter or receiver, the second loop antenna having a second resonant frequency, with a second frequency of peak response, and a second bandwidth distributed around said second resonant frequency, wherein the second loop antenna and the first loop antenna are mutually conductively connected only along a common ground path; wherein, said first loop antenna and said second loop antenna are exclusively magnetic field coupled such that said first antenna, and said second antenna have a coupled frequency response with a coupled frequency of peak response not equal to said first or second frequency of peak response, and a coupled frequency response bandwidth distributed about said coupled frequency of peak response, where the extent of the coupled frequency response bandwidth is greater than the sum of said first bandwidth and said second bandwidth; and a protective epoxy in which said first antenna, said second antenna, and said exclusive magnetic coupling means are embedded.
