Design Methodology for Conformal U-Shaped Series Fed Microstrip Antenna Array

The paper proposes a systematic approach for the  design of a conformal U-shaped series-feed microstrip antenna array (US-SFMA) using true time delay phase shifters. The presented study describes the design procedure of conformal SFMA without the use of additional element to tune its spectral and radiation performance. This restores the resonant frequency and hence the S11 response of the array on conforming it on a cylindrical surface by phase compensation technique, thereby enhancing its gain optimally. The paper proposes a systematic approach for the  design of a conformal U-shaped series-feed microstrip antenna array (US-SFMA) using true time delay phase shifters.
