The Effect of Dielectric Loss Tangent On Radiation Characteristics of Co- Axial Feed Rectangular Patch Antenna
The substrate permittivity and loss tangent are critical parameters in controlling band width, efficiency and radiation pattern of micro strip patch antenna. Present paper rectangular patch antenna is designed using a wide range of dielectric materials having same permittivity but with different loss tangent values. A comprehensive study of radiation characteristics of this rectangular patch antenna is investigated. Results such as resonance frequency, bandwidth, gain, return loss, input and impedance are presented.
