TLDR
A novel broadband stacked E-shaped patch antenna is proposed, which has an input impedance bandwidth better than the conventional E- shaped microstrip patch antenna, and the radiation patterns are found to be relatively constant throughout the whole band.Abstract:
A novel broadband stacked E-shaped patch antenna is proposed in this paper. The proposed antenna has an input impedance bandwidth of about 38.41%, better than the conventional E-shaped microstrip patch antenna, which has an input impedance bandwidth of 33.8%. Through the use of the washer on the probe of the stacked patch antenna, the input impedance bandwidth is improved further to 44.9%. The radiation patterns are found to be relatively constant throughout the whole band. Comparisons of these antennas are presented in this paper.read more

Hugo Pues,A. Van de Capelle +1 more
TL;DR: In this paper, an accurate and numerically efficient model for the rectangular microstrip antenna is presented, which concerns a transmission-line model which features the following three major improvements with respect to earlier such models: the mutual radiative coupling (both real and imaginary parts) between the equivalent slots is fully taken into account; the influence of the side slots on the radiation conductance is taken implicitly; simple analytic expressions are introduced for all relevant model parameters.
