Abstract
Abstract
A conformal wing-shaped patch (WSP) antenna is designed and investigated in this paper. Coplanar waveguide (CPW) feed is used to get high impedance matching and better radiation pattern. The WSP antenna is designed on Kapton polyimide substrate material measuring 20 × 30 × 0.1 mm3. It offers the impedance bandwidth of 630 MHz (6.55 GHz -7.18 GHz), 560 MHz (9.80 GHz -10.36 GHz), 560 MHz (9.80 GHz -10.36 GHz) at resonant frequencies 6.97 GHz, 10.12GHz, 15.78GHz respectively. The reflection coefficients are obtained at -17.42 dB, -16.39dB, -18.23dB for the resonant frequencies. To analyze the conformability of the WSP antenna, the model is tested by mounting on the guided missile. The performance of the antenna is good and small deviations are observed with a shift of 30 MHz, 120MHz, 380MHz in the reflection coefficient. The compactness and conformal design with multi-band support proves the antenna suitable for future military applications.
