Analysis of Probe-fed Circular Microstrip Patches Backed by Circular Cavities

Design and Modeling of S Band Circular Patch and Ka Band Horn Antenna, Integration with Future Multifunctional Radio over Fiber Network

“…Circular patch antennas are attention seekers in both single elements [20]- [25] and in arrays [26] and [27]. Cavity Model [21] [24] [25] can be used for conveniently analysis of circular patch antenna.…”

“…Cavity Model [21] [24] [25] can be used for conveniently analysis of circular patch antenna. Circular patch antenna occupies less space as compared to rectangular patch antenna.…”

Rigorous analysis of probe-fed printed annular ring antennas

“…This yields a large computational savings as compared to the rectangular probefed patch. The derivation and evaluation of the individual matrix elements follows [8].…”

“…The annular ring attachment mode implemented here is an application of the concept originally proposed by Aberle [5], [7], [8] for a circular-patch geometry. In this approach, an attachment mode appropriate to the geometry under consideration is derived from the corresponding cavity model, assuming a uniform filamentary source.…”

“…Note, that for the purposes of testing the operator equation, the part of the testing functions which exist on the probe feed is not assumed to be filamentary, but includes the radius of the probe [5], [7], [8]. This adds to the accuracy of the method, since the radius of the probe is considered; however, it removes the symmetry of the attachment mode portion of the system matrix.…”
