Abstract
Conference Title: 2016 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting Conference Start Date: 2016, June 26 Conference End Date: 2016, July 1 Conference Location: Fajardo, PR, USA High gain tunable annular ring antenna structure for WiFi band are reported by stacking passive elements over an active element realized on a composite substrate of ferromagnetic nanoparticles or ferroelectric thin films with FR4 baseline substrate. Low Coercivity material with high refraction index, low loss, and high saturation moment are attractive in realization of tunable small sized radio frequency (RF) circuits. The FeCo antenna designed shows 26% tunability per 1kG of applied DC magnetic field. The Finite Element Method (FEM) computational method is used for designing and performance optimizing to achieve high gain. The FeCo was characterized to have permeability of (μr>10, tarδ<0.2) while the BST have permittivity of ([straight epsilon] r >150, tarδ<0.02). This paper addresses the use of Fe60Co40 soft magnetic nanoparticles to realize high gain tunable stacked antennas for WiFi band and possible improvements using manganese-doped Ba0.8Sr0.2TiO3(BST) soft ferroelectic thin films.
