Optimization of Microstrip Patch Antenna on C band and X band with Radome Effect

Microstrip patch antenna is versatile and vast field of antenna theory. A particular aspect of work done in this field is presented. In addition a different antenna configuration that improve electrical performance and sustainability is described. We analyzed microstrip antenna in IE3D by finite moment of method. The proposed antenna designs have been analyzed between 1GHz to 20 GHz. When the proposed antenna design of different geometries (i.e. Rectangular, Triangular and Circular) were examined for the two dielectrics i.e. RT duroid 5870 with dielectric constant 2.33, loss tangent 0.0005 and Ferro A6M, LTCC with dielectric constant 5.9, loss tangent 0.0012 the results are : For rectangular geometry return losses = -22 dB, VSWR = 1.238, Z = 60.83 Ω at 6 GHz; For triangular geometry return losses = -12.2 dB, VSWR = 1.648, Z = 78.35 Ω at 10 GHz, For circular geometry return losses = -15.5 dB, VSWR = 1.409, Z = 36.65 Ω at 10 GHz.
