Cylindrical conformal microstrip bow-tie antennas

Abstract

Microstrip bow-tie antenna (MBA) conformal to cylinder with small curvature radius is studied. The simulation of return loss and radiation patterns of one-element cylindrical conformal microstrip bow-tie antenna (CCMBA) and two-element CCMBA array is presented. It is shown that CCMBA with small curvature radius can also achieved a large bandwidth, though the resonant frequency and the radiation patterns are changed. Calculated results are in good agreement with measurements.
