Design of satellite launcher antenna for efficient link budget

A satellite launcher array has been designed and its performance has been investigated. Based on 10 dB return loss, the bandwidth of the simulated S₁₁ is 10.26 % (2.13∼2.36 GHz) at S-band and 14.5 % (5.28∼6.1 GHz) at C-band, respectively. The tilted angle (T = 45°) increases the directivity from 4.9 dBi to 6.29 dBi (1.39 dB up) at S-band, from 4.821 dBi to 6.45 dBi (1.63 dB up) at C-band. All over the angle (θ,Φ), the possibility when the gain is below ∼12dB for S band is 2.246 % in the E plane, and 2.09 % in the H plane, respectively.
