In this paper, a monopole UWB broadband antenna is designed, fabricated, and measured for wireless communication networks. The initial radiator model of the proposed has short-sleeve shape, to expand impedance bandwidth, right left angles are subtracted symmetrically from lower half radiator. matching improved by etching slots in feed line adding L-shaped patches on both sides line. results show that miniaturized system can cover WiFi 7(2.4–2.484 GHz, 5.15–5.35 5.725–5.825 5.925–7.125 GHz),...
In this paper, a WiFi-UWB multiband monopole antenna is designed, fabricated, and tested based on the characteristic mode theory, which mainly consists of an L-shaped metal, "ok"-shaped metal radiator, T-shaped patch.The substrate dimensions are 40 × 43 1.6 mm 3 , featuring rectangular ground plate at substrate's bottom.The upper surface composed ring curved finger-shaped metal.To improve impedance matching broaden bandwidth, strategic modifications implemented.Specifically, slot introduced...
In this paper, a dual-port ultra-wideband (UWB) MIMO antenna is proposed, featuring highly compact structure with dimensions of only 25 × 36 1.6 mm 3 .The designed comprises two racket-shaped monopole antennas and defective floor.Cross slots on the original T-shaped floor impede coupling current flow, significantly enhancing isolation to achieve over 20 dB across most frequency bands.The operates at frequencies from 2.74 ∼ 14.8 GHz, meeting stringent design criteria for UWB...
Abstract: Introduction: This research presents an 8-port 3.6 GHz multiple-input multiple-output (MIMO) cell phone bezel antenna for 5G mobile communication. Method: Each unit consists of a Chinese character "卫". In order to reduce the mutual coupling between MIMO units, defective ground structure (DGS) decoupling is employed in this research. By increasing DGS antenna, adjacent greatly reduced. The transmission coefficient and surface current distribution account structure's efficacy....
This paper proposes a high isolation transparent ultra-wideband (UWB) multiple-input multiple-output (MIMO) antenna based on characteristic mode theory. The consists of four coplanar waveguide (CPW)-fed UWB monopoles, each which is hollowed out into mesh structure guided by feature theory with metal and substrates, an excitation added at the feed point to successfully excite modes 1, 3, 5, 7. These excited cover frequency range 1.7-13 GHz. An orthogonal layout adopted make more compact....
