A continuously steerable patch antenna employing liquid metal is presented. The proposed employs a novel tunable ground plane together with parasitic steering to steer the direction of main beam. consists permanent region, made from copper, and two regions formed metal. channels were fabricated using 3D printing technology. By injecting into channels, can provide continuous beam −30° +30° in elevation plane, while achieving low side lobe level performance combined scan loss performance. Such...
A switchable multibeam antenna array with a compact planar feeding network is presented. Operating within 1 GHz bandwidth at 28 GHz, this 4 × can generate onebeam, two-beam and four-beam patterns based on two phase states, which are controlled by the reconfigurable network. The whole structure validated simulating in CST Studio. promising candidate millimeterwave Massive MIMO for applications where multiple beams required simultaneously.
Abstract In this paper, a reconfigurable transmitarray unit cell using liquid metal is presented. It consists of three conducting layers where the geometries resonators, on different layers, differ and consist an arrow shape together with rotated split rings. The arrow‐shaped layer has capability to convert polarization incoming waves by 90°. ring upper lower have same dimensions but orientations (horizontal vertical polarization). Several fluidic channels are placed beneath/above layers....
Rapid prototyping can quickly realize the forming of parts through principle melt accumulation, without complicated processing technology.And it has a profound influence on development manufacturing industry.Rapid technology is very suitable for complex shapes and precision processing, widely used in field mold trial production new products.Fused deposition molding (FDM) an important branch rapid technology.It does not require high working environment, noise volume are also small, so home,...
In this paper, we designed, fabricated and measured a novel liquid metal beam switching Bull's Eye antenna, operating at 10.3 GHz. The antenna was fed by WR-90 waveguide. We the based on 3D printing technology. main of able to switch ±13.5°, injecting/removing from designed channels. At GHz, realized gain could reach 11.3 dB with side lobe level - 9.2 dB. 10-dB return loss bandwidth 320 MHz. Within frequency range, above
As the core moving part of laser cutting machine, beam quality has a very important impact on dynamic and static performance processing accuracy machine. This paper uses Solid Works to build model F3015 select 8 design variables appropriate constraint conditions, take economic index as objective function carry out lightweight beam. The results show that mass is reduced by 15.9%, total deformation 10 .5%.
In this paper, we propose a simple approach for enhancing the realized gain of straight corrugated antenna. The involves placing dielectric cube above We investigate into how thickness affected antenna gain. find out that by 42 mm × 56 60 on top antenna, is improved 5.1 dB, to reach 17.7 dBi at 10 GHz.
