“…Planar multilayer transmission lines, such as microstrip lines have been applied in many microwave and millimetre-wave circuits [27]. In some multilayered structures, these transmission lines are even combined to form circuit components.…”

Abstract-In this paper, a novel ultra-wideband switched-beam antenna system based on 4×4 two-layer Butler matrix is presented and implemented to be used in hostile environment, such as underground mines. This matrix is based on the combination of a broadband twolayer slot-coupled directional coupler and a multilayer slot-coupled microstrip transition. With this configuration, the proposed matrix was designed without using any crossovers as used in conventional Butler matrices. Moreover, this new structure is compact and offers an ultra-wide bandwidth of 6 GHz. To examine the performance of the proposed matrix, experimental prototypes of the multilayer microstrip transition and the Butler matrix were fabricated and measured. Furthermore, a three 4-antenna arrays were also designed, fabricated and then connected to the matrix to form a beamforming antenna system at 3, 5.8 and 6 GHz. As a result, four orthogonal beams are produced in the band 3-9 GHz. This matrix is suitable for ultrawideband communication systems in confined areas.

“…Recently, there has been increasing interest in multilayer bandpass filters to meet the challenges of size, performance, and cost requirements [18][19][20][21][22][23][24][25]. However, most of the multilayer filters were analyzed by quasi-static or full-wave methods [10,18], and their designs have been limited to the quarter-wavelength coupled-line sections only [22].…”

Abstract-This paper presents the analytical design formulas for the bandpass filters which are built on the asymmetrically coupled-line conductor-backed coplanar transmission lines (CBCTLs) in multilayer configuration. The full-wave simulation is employed to characterize the far-field patterns of space-wave and surface-wave radiations as well as the frequency-dependent conductor, dielectric, and radiation losses. Good agreement among the results of full-wave simulation, transmission-line model, and measurement justifies the design procedure and validates the analytical design formulas. By properly placing the dielectric materials in multilayer configuration, a bandpass filter for minimizing the radiated power loss and improving the stopband characteristic can be achieved.

“…The MCL was introduced as a good candidate for filter applications in [2], since it offers a wider range for a nearly constant characteristic impedance and provides more effective capacitive coupling between the resonators by locating them on the two sides of the substrate [2], [4]. Some MCL coupling structures for filters have been proposed in [3].…”

-The design of compact multilayer coplanar line bandpass filters is presented. These very compact filters make use of the two sides of the substrate of the modified coplanar line. In addition, a transmission zero has been introduced to the filter response, either by extending the metalization under the ground planes, or by employing additional capacitive coupling between the different parts of the filter structure. A good agreement between the simulated and measured responses has been achieved.
