Abstract: A novel slot aperture stacked patch antenna is presented for wireless communication applications and its performance evaluation is examined with change in the dimensions of radiating elements. Stacked patch antenna is proposed to increase the narrow bandwidth, radiation efficiency and directivity. The antenna consists of one driven patch and one parasitic patch on two dielectric substrates of RT-duroid (εr = 2.2) and FR4 (εr = 4.4) materials. The antenna behaviour is explained through parameter study using finite element method and output parameters are presented in detailed manner.

Keywords: substrate materials; slot aperture antenna; stacked patch antenna; radiation efficiency; directivity; wireless communications; performance evaluation; bandwidth increase; finite element method; FEM.
