Summary:
The radiation characteristics of a microstrip patch antenna versus the grounded dielectric substrate size are mainly determined by the effective dielectric constant of a grounded dielectric substrate. Excellent agreement between the simulation and experimental results shows that the largest front-to-back ratio due to the large broadside gain and the minimum back lobe gain is obtained when the substrate size is 0.8 λ0.
