Effect of Curvature on the Performance of a Cylindrically-Conformal Cavity-Backed E-patch AntennaAbstract
The behavior of a cavity-backed Epatch antenna placed conformal to a cylindrical conducting surface is explored through simulations and experiment to determine the effects of curvature on antenna performance. It is shown that introducing a cavity backing reduces the bandwidth of an E-patch, but that the curvature of a conformal antenna partly compensates for the loss of performance. It is further shown that the curvature of a conformal antenna strongly affects both the co- and cross-polarization gain patterns.
