Abstract

This paper presents the design, simulation, and fabrication of a miniaturized millimeter-wave band-stop filter (BSF) on microstrip technology. The proposed arrangement is based on the concept of transversal interference of signals, and is realized as a pair of parallel transmission lines with the appropriate characteristic impedance and electrical length. Such scheme provides sharpening signal discrimination without resonator structures additional to the filter. The filter is fabricated on a ROGERS RT/Duroid 5880 substrate, selected for its favorable properties at high frequencies, including a thickness of 0.13 mm, a relative dielectric constant of 2.2, and a loss tangent of 0.0009. The optimized design was validated through electromagnetic simulations by two types of electromagnetic solvers, and then fabricated and measured by coplanar waveguide (CPW) probe to confirm its practical performance.

Abstract

We introduce a novel, compact bandpass filter (BPF) that employs Ring coupling through a microstrip design. This filter features a ring resonator that mainly relies on capacitive coupling to achieve its resonant characteristic. The results from experimental fabrication confirmed the expected performance of the filter, showing strong agreement between the simulated and measured S-parameters. The filter is built on a RO4003C substrate that is 1.52 mm thick, with a dielectric constant of 3.38 and a loss tangent of 0.0027. Designed for a center frequency of 5.72 GHz and a bandwidth of 930 MHz, it exhibits low insertion loss and effective signal rejection, as supported by advanced electromagnetic simulations. This flexible and efficient filter design represents a significant step forward, offering great potential for innovative communication systems and wireless power transmission, especially when integrated with 5.8 GHz straight-through antenna arrays for wireless energy harvesting.

Abstract

This paper presents the design, simulation, and achievement of an optimized 64-element antenna array based on Wilkinson power divider operating at 24 GHz. The whole circuit is mounted on a Rogers RO4830 substrate with a thickness of 0.127 mm, copper cladding thickness of 0.018 mm, dielectric constant of 3.24, and a loss tangent of 0.0033. Using advanced design system (ADS) from Keysight, the combiner is meticulously simulated to achieve efficient power combination with minimal insertion loss, excellent impedance matching, and high port-to-port isolation. The design ensures that power from multiple input ports is effectively combined into a single output port, suitable for high-frequency applications. Simulation results at 24 GHz confirm optimal performance, and validation corroborates the accuracy of the ADS-based simulations. The proposed design demonstrates reliability and efficiency for integration into modern communication radar systems operating at millimeter-wave frequencies.
