“…The split ring resonator (SRR) has been used for miniaturizing the antenna size as proposed in [16,17]. Based on this, the magnetic field perpendicular to the ring (loop) induces a current in the ring, as a result, the induced current will create magneto dipoles.…”

“…This technique can compensate for degradation of the bandwidth, which leads to miniaturizing the antenna size. However, in previous works [16,17], the metamaterial substrate layers were thick and cannot be used in a planar circuit whereas the proposed magneto-dielectric substrate is thin enough to use in the planar circuit. As shown in Figure 1, under specific boundary conditions, zy-plane walls are perfect magnetic conductors (PMCs), xy-plane walls are perfect electric conductors (PECs) and zx-ports, and the effective parameters of the proposed unit cell are extracted using the method reported by Shi et al as shown in Figure 2 [18].…”

In this paper, a miniaturized Ultra High Frequency Radio Frequency Identification (UHF-RFID) tag-based sensor antenna using a magneto- dielectric substrate (MDS) for wireless identification and sensor applications is presented. Two models of RFID tag-based sensors are designed, fabricated and measured. The first model uses two RFID tags; both of the tags are incorporated with two RFID chips. A passive sensor is also integrated in one of the proposed tags to serve as a sensor node, while the other tag is used as a reference node. Based on the difference in the minimum power required to activate the reference and sensor nodes, the sensed data (temperature or humidity) can be determined. The magneto-dielectric substrate layer is placed underneath the patch antenna to reduce the size of the proposed sensor by about 75% compared to a conventional RFID tag-based sensor. The magneto-dielectric layer is thin enough to embed in the planer circuit. To reduce the size of the proposed sensor, a multi-port tag for including the reference and sensor node in one antenna is also presented. The proposed RFID tag-based sensors have several features such as small size, they are completely capable for two objectives at the same time and easy to integrate with a planer circuit.

“…One major drawback in a patch antenna is its large size. Several different techniques have been proposed in literature for miniaturizing the antennas [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. In [2][3][4][5], miniaturization is achieved by using geometrical modification.…”

“…Another technique, based on magneto-dielectric substrates, has been used for miniaturizing microstrip-patch antennas. Researchers in [7][8][9] have created a magneto-dielectric substrate using an array of parallel split-ring resonators (SRRs). Employing these array leads to a better reflection coefficient bandwidth as compared to high-permittivity substrates [6].…”

“…A planar magneto-dielectric substrate has been proposed in [10][11][12][13][14][15]. Although these types of substrates are planar, the antenna efficiency is less than the one with un-planar magneto-dielectric substrate [7][8][9]. Recently, a new fabrication technology has emerged for the design of polymer-based magneto-dielectric composite substrates for antennas, such as nickel and ferrite [16,17].…”

Miniaturized Circularly-Polarized Patch Antenna Using an Artificial Metamaterial Substrate

An artificially two-dimensional metamaterial (ATDM) substrate is proposed as an artificial metamaterial high-constitutive parameter substrate for miniaturizing of a circularly-polarized microstrip antenna. In a circularly-polarized antenna, the electric and magnetic field directions are changing, which requires a two-dimensional metamaterial unit cell. The presented ATDM substrate raises the permeability and permittivity of the underneath substrate for a circularly-polarized patch antenna, and it is constructed of periodically arranged split-ring resonator (SRR) circuits implemented in a low permittivity dielectric underneath substrate. The ATDM attains equal permittivity and permeability material (ε r ∼ = μ r), which neutralizes the destructive effect of the increased permittivity on the bandwidth. In addition, the ATDM structure is implemented in printed circuit board technology. The area of the ATDM antenna at 2.45 GHz is approximately 75% smaller than a usual microstrip antenna. The proposed antenna bandwidth is enhanced compared to the antennas with high-permittivity substrates. The proposed ATDM substrate antenna is fabricated and measured, and comparisons show good agreements between simulated and measured results.
