Cylindrical stacked patch antennas for wireless communication

The stacked cylindrical patch antenna proposed in this paper overcomes the bandwidth limitations of the single patch version. The analysis of the antenna was done by using the method of moments in the spectral domain. The GIDMULT algorithm for the calculation of the Green's functions of a general cylindrical multilayer structure in the spectral domain was incorporated into a moment method program, which was used to compute the input impedance and the radiation pattern. For a VSWR of <2:1 the reported bandwidth is more than 10%.
