Abstract
In this paper, a new cavity-backed antenna configuration,
called strip, slot, air, inverted patch (SSAIP) is
proposed. The SSAIP is the cavity-backed version of the
standard strip, slot, foam, inverted patch (SSFIP)
antenna concept, and this paper compares
the electrical performances of both types of antennas.
Results reveal that similar to their SSFIP
counterparts, SSAIP antennas also exhibit large frequency
bandwidth but now combined with clean and versatile
radiation patterns and can thus be used in broadband
communication applications. The analysis of these
antennas is carried out with a specific
integral equation formulation, described in the paper.
To facilitate the physical understanding of the new
structure, an equivalent filter model of the real SSAIP
antenna is also derived. This equivalent model allows
standard filter design techniques to be used for an easy
electrical design of the antenna. In addition to
theoretical results, experimental results are ...
