Patent ID: 6924773

Claim:
An integrated dual band antenna system comprising: an H-field antenna comprising: (i) a first shielded section having a first end and an opposite second end, the first end of the first shielded section being adapted to receive one of a first radio frequency signal or a second radio frequency signal different than the first radio frequency signal; (ii) a second shielded section having a first end and an opposite second end; and (iii) an unshielded section disposed between the second ends of the first and second shielded sections forming an unshielded gap; a first input frequency filter electrically connected to the first end of the first shielded section, the first input frequency filter passing therethrough the first radio frequency signal; a second input frequency filter electrically connected to the first end of the first shielded section, the second input frequency filter passing therethrough the second radio frequency signal; a first output frequency filter electrically connected to the unshielded section, the first input frequency filter and first output frequency filter being matched to one another so as to pass therethrough the first radio frequency signal; a second output frequency filter electrically connected to the unshielded section, the second input frequency filter and second output frequency filter being matched to one another so as to pass therethrough the second radio frequency signal; and an E-field antenna electrically connected to the second output frequency filter; the integrated dual band antenna operates in a first mode wherein the first radio frequency signal passes through the first input frequency filter, the first shielded section, the first output frequency filter, the second shielded section and generates an H-field transmission pattern in both the first and the second shielded sections; the integrated dual band antenna operates in a second mode wherein the second radio frequency signal passes through the second input frequency filter, the first shielded section, the second output frequency filter and radiates an E-field via the E-field antenna.
