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, Broadband Multi-Shaped Metasurface Circularly Polarized Antenna With Suppressed Non-CP Radiation Modes(2023-01-01); In this research, a multi-shaped metasurface broadband circularly polarized (CP) patch antenna with parasitic elements is proposed for 5G new radio (NR) applications. The proposed metasurface CP patch antenna comprises triple-layered substrates without air gap. The upper layer sits with multi-shaped metasurface elements and parasitic patches. The middle layer consists of an L-shaped slot functioning as the ground plane, and the lower layer contains a microstrip and a fan-shaped stub functioning as the feed line. The proposed metasurface CP patch antenna with parasitic elements is evaluated using characteristic mode analysis (CMA). The CMA results indicate that the modal significance of Modes 1 and 2 of the multi-shaped metasurface CP antenna are orthogonal, giving rise to circular polarization. The non-CP radiation of Modes 3 and 4 are suppressed by using the multi-shaped metasurface elements and parasitic patches. The measured impedance bandwidth and axial ratio bandwidth are 42.85% (3.4 - 4.9 GHz) and 38% (3.27 - 4.6 GHz), achieving the maximum gain of 7.23 dBic at 3.7 GHz. The experiments demonstrate that the multi-shaped metasurface CP patch antenna with parasitic elements is suitable for 5G NR wireless applications. The novelty of this study is attributed to its utilization of multi-shaped metasurface elements and parasitic patches, which effectively suppress non-circularly polarized radiation modes. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Enhancing Bandwidth of Circularly Polarized DRA Using Embedded Slot-Coupled Patch(2024-01-01); Konpang, JessadaThis paper proposes a bandwidth enhancement technique for circularly polarized (CP) dielectric resonator antenna (DRA) using the embedded slot-coupled patch. The proposed CP DRA for mid-band 5G applications consisted of an aperture-coupled feed, a dice-shaped dielectric resonator (DR), and an embedded slot-coupled patch. A slot-coupled feed included cross-aperture ground plane (upper substrate) and microstrip-line feed (lower substrate). The dice-shaped DR sits at the center of the cross-aperture ground plane. The slot-coupled patch was embedded into DR for bandwidth enhancement. The DR usually functioned as a resonance cavity, producing TEll1 mode. The embedded slot-coupled patch can generate the resonance frequency mode (TM01 and TMl0) at a higher frequency, resulting in a wide reflection coefficient bandwidth and ARBW. The results of simulation reflection coefficient bandwidth and ARBW at center frequency (3.5 GHz) achieved 44% (3.12 - 4.66 GHz) and 36.57% (3.23 - 4.51 GHz). The peak RHCP gain was 8.7 dBic at 4.5 GHz with right-hand circular polarization, rendering the proposed CP DRA with embedded slot-coupled patch suitable for mid-band 5G wireless networks. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, CMA-Based Four-Element Broadband Circularly Polarized Octagonal-Ring Slot Antenna Array for S-Band Satellite Applications(2022-01-01); This research proposes a low-complexity and low-profile four-element circularly polarized (CP) octagonal-ring slot antenna array with sequentially-rotated feed network for S-band satellite applications. The proposed antenna array is characterized by characteristic mode analysis (CMA). One single element of the CP octagonal-ring slot antenna array consists of a C-shaped monopole on the upper layer functioning as the radiating patch; and an octagonal-ring slot patch on the lower layer functioning as the ground plane. The four elements are connected by a sequentially-rotated feed network to enhance the impedance bandwidth (IBW), axial ratio bandwidth (ARBW), and gain. Simulations are performed, and an antenna prototype is fabricated and experiments carried out. The measured IBW and ARBW at the center frequency of 2.4 GHz are 91.6% (1.8 - 4 GHz) and 84.5% (1.97 - 4 GHz), with the maximum gain of 7.8 dBic at 3.3 GHz, rendering the proposed four-element CP octagonal-ring slot antenna array with sequentially-rotated feed network operationally suitable for S-band satellite communication. The novelty of this research lies in the use of CMA to characterize the circular polarization of the octagonal-ring slot antenna array; and the sequentially-rotated feed network to enhance the IBW, ARBW, and antenna gain of the four-element CP octagonal-ring slot antenna array with sequentially-rotated feed network.
