Broadband microstrip antenna located on a cylindrical surface

This paper presents the results of a study of changes in the characteristics of planar broadband microstrip antenna, after it is located on a cylindrical surface. The planar microstrip antenna has a VSWR<;2 and gain from 8.3 to 9.0 dB in the band of 1.8-2.2 GHz. As follows from the studies after location on the cylindrical surface, the antenna retains these characteristics are almost unchanged when a large bending radius of surface. The conformal microstrip antenna with radius of cylindrical surface R=500 mm has VSWR less than 2 in the frequency range of 1.813-2.207 GHz (22.2%). In the frequency range the gain has a value from 7.4 to 8.8 dB.
