Item type:Publication, Broadband Two-Array Metasurface-Gridded MIMO Antenna with Dual-CP Bi-Directional Capabilities(2025-01-01); Konpang, JessadaThis study presents a novel two-array MTS-gridded MIMO antenna with dual circular polarization (CP) bidirectional capabilities for full-duplex communications. The proposed antenna consists of two mirrored clusters, each comprising a single-element antenna formed by a 3 × 4 MTS-gridded element array, a circular patch, and a ground plane. The antenna demonstrates a wide measured return loss bandwidth (RLBW) of 56.46% (5 - 8.67 GHz), axial ratio bandwidth (ARBW) of 18.15% (6.26 - 7.44 GHz), and strong isolation below -22 dB. Peak gains of 6.5 dBic and 6.55 dBic were observed at 6.6 GHz and 6.54 GHz for Ports 1 and 2, respectively. Furthermore, the low envelope correlation coefficient (< 0.005) and high diversity gain (> 9.985 dB) validate its effectiveness for multi-port applications. The bidirectional radiation pattern and dual circular polarization support simultaneous transmission and reception, making the design well-suited for full-duplex MIMO operation. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Dual-Band CP Metasurface-Array Antenna with Sequential-Phase Feed Network for C-Band Operation(2026-01-01); Supreeyatitikul, NathapatThis paper presents a four-cluster dual-band circularly polarized (CP) metasurface (MTS)-array antenna integrated with a sequential-phase feed (SPF) network for C-band applications. The antenna is implemented on dual-layer FR-4 substrates, incorporating both big- and small-sized MTS-array elements per cluster, with a tilted square-slot ground plane and microstrip-line feed. The SPF network excites each cluster with equal amplitude and 90<sup>°</sup> phase shifts, significantly enhancing return loss bandwidth (RLBW), axial ratio bandwidth, and realized gain. The simulated results demonstrate RLBW of 3.08 - 4.51 GHz and 4.94 - 8 GHz, and ARBWs of 3.08 - 4.66 GHz and 5.27 - 6.42 GHz for the lower and higher operating bands, respectively. The corresponding highest RHCP gains are 6.15 dBic at 3.8 GHz and 4 dBic at 6 GHz. The proposed antenna design achieves bi-directional radiation patterns and shows substantial performance improvements over conventional dual-band CP MTS-array antennas. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Prism-Shaped Dielectric Resonator Circularly Polarized Antenna with Loop-Shaped Metasurface-Enhanced Reflector(2025-01-01); Konpang, JessadaThis paper proposes a prism-shaped dielectric resonator (DR) -based antenna with circularly polarized (CP) characteristics for C-band wireless systems. This antenna comprised a prism-shaped DR and single-layer substrate. The prism-shaped DR is on the upper-side substrate. Besides, a rod-shaped probe was plugged into a DR and connected by an SMA connector on the lower-side substrate. A loop-shaped metasurface-enhanced reflector is employed to improve bandwidth (i.e., RLBW and ARBW) and antenna gain. A regularly spaced array of 7 × 7 loop-shaped metasurface unit structures is positioned on the upper substrate side. The simulation RLBW and ARBW results at 5.8 GHz (center frequency) are 34% (5.22 - 7.2 GHz) and 16% (5.27 - 6.2 GHz). This antenna radiates left-hand circular polarization with an optimal maximum gain at 5.5 GHz of 6.7 dBic, making it suitable for C-band wireless networks. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Two-Port Circularly Polarized Slot-Coupled Antenna Using Novel AMC Structure(2025-01-01); Konpang, JessadaThis research introduces a two-port circularly polarized (CP) slot-coupled MIMO antenna with an novel artificial magnetic conductor (AMC) reflector for Vehicle-to-Everything (V2X) technology. The proposed antenna comprises two layers separated by an air gap: the upper layer includes the dual-element slot-integrated MIMO antenna with microstrip-line feeds and defected ground structures (I-shaped slots) for coupling reduction, while the lower layer integrates an 8 × 8 array of AMC units. The AMC enhances gain and improves radiation properties through its reflective behavior. Measured results confirm the antenna's suitability for V2X applications, achieving a wide return loss bandwidth (RLBW) of 32% (4.72 - 6.61 GHz), axial ratio bandwidth (ARBW) of 21.18% (5.2 - 6.45 GHz), and isolation greater than 19 dB. The antenna attains a peak gain of 8.6 dBic at 5.9 GHz, with an envelope correlation coefficient below 0.003 and diversity gain exceeding 9.98 dB. The key innovation of this work lies in the combination of CP slot-integrated MIMO design with a novel AMC structure to enhance gain and isolation, making it highly effective for V2X wireless networks in modern vehicular communication networks. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Wideband Circularly Polarized Sequentially-Rotated Cubic-Shaped Dielectric Resonator Array Antenna(2025-01-01); Konpang, JessadaThis study proposes a cubic-shaped dielectric resonator (DR) broadband circularly polarized (CP) array antenna for S-band networks. The design includes 2 × 2 cubic-shaped DR units and a substrate. The upper and lower substrates feature a split-annular aperture ground plane and a sequential-phase feed. Employing the sequential-phase feed, the proposed array antenna aims to enhance performance metrics, including RLBW, ARBW, and antenna gain. Simulation results indicate a RLBW of 56.25% (2.25 - 3.6 GHz) and an ARBW of 43.33% (2.38 - 3.42 GHz). The optimal gain achieved is 9.14 dBic at 3.3 GHz. Furthermore, the array antenna demonstrates right-hand circular polarization (RHCP) characteristics, rendering it suitable for S-band technology.
