| Popis: | Electroacoustic radiation properties of four element linear array and 2×2 element planar array of square patch microstrip antenna immersed in warm plasma are studied in this paper. Far-zone field expressions of the array antennas for electromagnetic as well as for electroacoustic modes are derived and patterns are plotted. The expressions are also obtained for radiation conductance, directive gain and efficiency of the antennas and the effect of electroacoustic waves in plasma is observed. Finally, the results of array antennas are compared with that of single element antenna. It is observed that the radiation properties of array antennas are changed considerably in plasma medium. |
