This article presents the miniaturization process of a rectangular patch RFID antenna. Based on an RFID antenna which is produced to be used on metal surfaces, a smaller antenna compatible with the Impinj Monza 4E chip was designed. In order to match the impedance of the chip, while maintaining a closer performance of the original antenna at 915 MHz, a magneto-dielectric substrate was used and a simulation was done using the CST MicroWave Studio® electromagnetic simulation tool. Moreover, the new design considers the factor of miniaturization in function of the intrinsic properties of the used substrate. Results show that a simple design was constructed and that was tuned to the desired frequency, matching the impedance of the chip.

“…Moreover, in case the antenna is mounted on a PEC ground plane, the condition is much stricter, typically ka<0.5 [6]- [8]. Approaches to miniaturization while maintaining antennas performance include: a) using fractal shaped objects [9]; b) applying dielectric or magnetic materials around radiating elements [3] (sometimes magneto-dielectric composites [10]); c) using optimization algorithms [3]; d) deploying lumped [3] or parasitic [11] elements around the main radiating element; e) enhancing the slow-wave behavior through periodic loading [12], etc. Recently there has been increased attention to incorporating electrically small periodic elements into the body of traditional structures [13]- [17].…”

A method is proposed to decrease the matching frequency of the recently introduced self-excited electromagnetic bandgap resonator antenna (SE-EBG-RA). The method is based on application of a metal shorting plate at the open end of the antenna which reduces the resonance. EBG unit cells are comprised of thick metal patches on top of a PEC-backed substrate, which are separated by tiny high aspect ratio (HAR) gaps. Two to six cells, each electrically much smaller than wavelength, are deployed in one dimension (1D) as a fragment of EBG microstripline with high radiation properties. Both open-circuit (OC) and short-circuit (SC) versions are presented, the SC version being electrically smaller. The miniaturization effect of dielectric loading of HAR gaps is also examined. The characteristics of proposed structures as improved radiators in terms of bandwidth, size, gain, and efficiency are demonstrated through parametric and comparative analyses and also prototyping. The efficiency, bandwidth, and footprint of the smallest dielectric-loaded version, a 2-cell SC SE-EBG-RA, are 96%, 3.5%, and 0.22 ×0.28 , respectively.

“…Magneto-dielectric (MD) materials are proposed to strongly reduce antenna size [1][2][3], with moderate values of relative permittivity and permeability. This allows to keep the material intrinsic impedance within an easy-to-be-matched range and the radiation resistance sufficiently high to guarantee the radiation performance.…”

“…An edgeshorted antenna is designed for wearable purposes as a miniaturized alternative to the square patch [2]. The tested MD substrate requires easier fabrication than film laminate [3], whose performance strongly depends on the precise size and position of the MD filling material.…”
