Abstract
New design of compact high gain microstrip antennas (MSAs) by loading ferrite ring in the substrate has been proposed in this article. Gain enhancement in two compact wideband MSAs, one exhibiting linear polarization and the other featuring circular polarization, is demonstrated using hybrid substrate. The proposed hybrid substrate is a combination of Roger's 6002 (εr = 2.94, tan δ = 0.0012) and Ferrite ring having εr = 10, μr = 14, dielectric loss tangent tan δe = 0.0017 and magnetic loss tangent tan δm = 0.0391. This ferrite ring loaded composite antenna results in a peak gain enhancement of about 4.46 dBi in a linearly polarized E-shaped MSA having bandwidth of 17.9%. In a similar fashion, a peak gain enhancement of about 3.61 dBi is exhibited on a standard dual-fed circularly polarized square MSA (S-MSA). Both E-shaped MSA and S-MSAs are fabricated and characterized for impedance and radiation pattern measurements exhibiting good corroboration with the simulated results.
