Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
131 words
A radiating element comprising: a microstrip including a ground plane first conductor; a dielectric microstrip substrate having first and second opposite sides, said first substrate side being bonded to said first conductor; a conductive resonator resident intermediate a microstrip feed line and a conductive dipole, said microstrip feed line spaced from said conductive resonator, said conductive resonator and said microstrip feed line being bonded to said second substrate side; a dielectric spacer having first and second opposite sides, said first spacer side being bonded to and over said second substrate side, to and over said conductive resonator and to and over said microstrip feed line; said conductive dipole being bonded to said dielectric spacer second side and spaced from said conductive resonator for optimizing bandwidth and efficiency of the radiating element.
Claim 2
Dependent Claim
131 words
A radiating element comprising: a microstrip including a ground plane first conductor; a dielectric microstrip substrate having first and second opposite sides, said first substrate side being bonded to said first conductor; a conductive resonator resident intermediate a microstrip feed line and a conductive dipole, said microstrip feed line spaced from said conductive resonator, said conductive resonator and said microstrip feed line being bonded to said second substrate side; a dielectric spacer having first and second opposite sides, said first spacer side being bonded to and over said second substrate side, to and over said conductive resonator and to and over said microstrip feed line; said conductive dipole being bonded to said dielectric spacer second side and spaced from said conductive resonator for optimizing bandwidth and efficiency of the radiating element.
Claim 3
Dependent Claim
32 words
The invention as defined in claim 1, wherein said first conductor, said conductive resonator, said conductive dipole and said microstrip feed line are all thin and long in comparison to their widths.
