“…Bulk ferrites, generally, have high saturation magnetization and dispersive magnetic losses [4][5][6] and needs strong external dc-bias fields to alter its permeability property [7], making it unsuitable for compact applications. Further, shift of operational frequency of antennas on ferrite substrates on application of external bias [8,9] causes difficulty in integrating it with other systems. Lately, artificial magnetodielectric substrates are used to overcome issues of high loss in ferrites.…”

Magnetodielectric substrate gives a new dimension for reducing the size of the planar antennas. In this article, the patch size is reduced by taking a substrate with nano-sized nickel ferrite inclusions in LDPE polymer matrix. The antenna is made to operate in X and Ku bands by engraving T slots along the resonant length of the patch. Structural modification of the substrate geometry as a step profile is incorporated along the slotted patch edges to enhance performance. The T-slots, along both the resonating lengths with the magnetodielectric stepped substrate show four resonant frequencies in both X-and Ku-bands with S 11 < −15 dB and a maximum −10 dB bandwidth of 22.4%. A miniaturization factor of 2.97 is obtained.

“…But, reports suggests that bulk ferrites generally have high saturation magnetization and dispersive magnetic losses [4][5][6] and needs strong external dc-bias fields to alter its permeability property [7], making it unsuitable for compact applications requiring higher efficiency. Further, shift of operational frequency of resonant devices on ferrite substrates due to application of external bias [8,9] causes difficulty in integrating it with other systems. Lately, artificial magnetodielectric substrates are used to overcome issues of high loss in ferrites.…”
