摘要
En 中文
The analysis of a capacitively fed wideband planar patch antenna array mounted on a cylindrical surface is presented. The antenna element used is in the shape of an octagon in which slots are placed on three of its sides. The elements are each fed by a small rectangular patch connected to a coaxial probe. On a cylinder of radius 100 mm, the single element is able to achieve an impedance bandwidth from 0.55 to 2.65 GHz, which is 131% of center frequency. When placed in an array environment, the bandwidth reduces slightly to 0.57-2.6 GHz, i. e., 128%. Simulation results, via two software packages, including parameters, radiation patterns, and gain of the single element as well as those of the array are provided. A single- and a double-element antenna fabricated are tested, and results are compared with those of simulations. This antenna structure provides stable radiation patterns across the entire pass-band.
