A Compact Wideband Antenna on Dielectric Material Substrate for K Band
AbstractA wideband modified S shaped electrically small microstrip patch antenna on Aluminium tri-oxide ceramic substrate is designed and analyzed in this paper. The proposed microstrip line fed miniature patch antenna designed by using high frequency electromagnetic solver and the computed results are analyzed by using finite element method. It is observed from the obtained results that, 830 MHz bandwidth (Return loss <-10dB), 2dBi average gain, 97.33% of average efficiency are achieved in the operating frequency from 19.97 GHz to 20.80 GHz for K band satellite applications. Furthermore, the co-cross polarization of the radiation pattern and the current distribution for E-H field is analyzed. Ill. 6, bibl. 18, tabl. 1 (in English; abstracts in English and Lithuanian).
