“…Recently it has played an important role in military applications where plasma can transmit, reflect, and absorb the electromagnetic waves under various circumstances. Based on the importance of plasma, there are many studies that investigated the behavior of plasma with respect to slot antenna [23][24][25][26]. According to [16], the results clearly show that the maximum radiation pattern and directivity can be obtained when the radius of the spherical slotted antenna covered by plasma layer is λ/2 and the optimum thickness for the plasma layer is λ/15.…”

The operation of the new proposed spherical slotted antenna covered by layers of dielectric material and plasma was analyzed numerically in this paper. By utilizing the Integra-functional equations method, the optimum thickness of dielectric material layer and suitable conditions which improve the operation of this antenna are analyzed here by MATHCAD. The thickness of dielectric layer must not be less or more than λ/6. Furthermore, the authors propose manipulating the operation frequency to enable such antenna to work in most circumstances.
