4(a) compared to that made to a circuit with the same design but produced using the classic commercial two-layered FR4 circuit board with similar dimensions (1.5 mm thickness), which can be seen in Fig.
"Under certain processing conditions, the die shear adhesion of the solderable polymer thick-film conductor, when printed directly on an FR4 board, approached that of the solder bond on copper-plated and etched FR4 boards."
The design example (Figure 1) has a 12-layer winding incorporating a primary and secondary winding produced using 2-ounce copper, FR4 PCB material and two identical substrates.
Here the comparison is illustrated in figure 6 without and with filling the metamaterial structure with FR4 material.
Response of specimens having two bolts in joints (FR4, FR6 and FR8) was asymmetric as can be seen both from Figures 5 and 7.
The fibre glass polymer resin (FR4) substrates are very often to be chosen for RF and microwave circuitry due to their inexpensive market price in comparison with other available substrates.
Two types of materials are used as substrate, FR4 (with relative permittivity [[epsilon].sub.r] = 4.4 and loss tangent [+ or -] = 0:02) and Rogers RT/duroid 5880 (with relative permittivity [[epsilon].sub.r] = 2.33).
The antenna is mainly composed of a single spiral arm, an FR4 board, a disc, and a coaxial pin.
With an FR4 four-layer substrate, the distance between the loop and the DUT can be fixed and vibration can be prevented.
The materials tested include two high Tg phenolic FR4 materials, six halogen-free FR-4 materials, some of which might also be considered mid-level high-speed materials, and four high-speed materials.
