Abstract

The effect of cylindrical dielectric capsulation on input and output performance of 2.5GHz half-wavelength dipole is investigated. A model of the capsulated antenna is presented and simulations are conducted according to different numerical values of parameters involving capsulation dimensions and dielectric constant. The antenna gain, directivity and reflection coefficient are calculated via finite element method in HFSS. Spline interpolation and polynomial curve fitting are applied to construct diagrams illustrating the capsulation characteristics. Some general conclusions of interest are obtained.
