Characteristics of a circular loop antenna in the presence of a coaxial conducting BOR attached to a planar reflector
The performance of the circular loop antenna (CLA) largely improves in terms of impedance matching and directive gain when a body of revolution (BOR)-type of reflector is placed symmetrically relative to the loop. The input impedance, reflection coefficient, VSWR, directivity, and radiation patt...

| description |
The performance of the circular loop antenna (CLA)
largely improves in terms of impedance matching and directive
gain when a body of revolution (BOR)-type of reflector is placed
symmetrically relative to the loop. The input impedance, reflection
coefficient, VSWR, directivity, and radiation patterns of a loop antenna
for cases of a reflector-hemisphere and a reflector-cone are
investigated in this letter. It is found that for a resonant loop, directivity
over 9 dB and VSWR less than 2 over a bandwidth of 48.5
MHz can be obtained. The study also shows that the characteristics
of the CLA depend mainly on the height of the loop over the
reflector and the total surface area of the reflector-body irrespective
of the body shape. |
