چکیده
Abstract This letter proposes a class of sine corrugated cavity resonators (SCCR). The SCCR can present slow‐wave features and provide dual‐mode (TE 104 TE 105 ) wideband responses with reasonable period depth. Based on it, compact high‐gain bandwidth‐enhanced slot antenna array is designed. high gain obtained seven radiation slots the achieved due to three modes being utilised. include one feed mode. Compared published works, desired be straightforwardly based SCCR. standard WR62 waveguide utilised antenna. For validation, direct metal 3D printing technology used fabricate it aluminium copper powders as comparison. Both measured results were discussed showed good agreement simulated ones.

Printed Wide-Slot Antenna Design with Bandwidth and Gain Enhancement on Low-Cost Substrate
This paper presents a printed wide-slot antenna design and prototyping on available low-cost polymer resin composite material fed by a microstrip line with a rotated square slot for bandwidth enhancement and defected ground structure for gain enhancement. An I-shaped microstrip line is used to excite the square slot. The rotated square slot is embedded in the middle of the ground plane, and its...

In In this paper, two low profile, single fed cavity backed slot antennas providing a circularly polarized (CP) wave are introduced. One of the antennas presents a right-handed CP (RHCP) wave, while the other one offers a left handed CP (LHCP) wave. The proposed antennas consist of a square shaped Substrtae Integrated Waveguide (SIW) cavity incorporatng two couples of radiating slots to radiate...
متن کاملDesign of a High-gain Cavity-backed Slot Antenna with Mushroom Cells and Bent Ground Walls
High gain antennas have many applications in wireless communication systems as they produce focused and narrow beamwidth, which allow for more precise targeting of the signal. Therefore, various gain enhancement techniques for antennas have been studied in the past decades [1–21]. Specifically there are three important methods to achieve this purpose: (1) Using antenna array, (2) Adding superst...
متن کاملImprovements in a High Gain Uwb Antenna with Corrugated Edges
In this paper, a novel corrugated structure at the edges of the Vivaldi substrate is presented. Compared with the Vivaldi antenna without corrugated structure, the new structure has a better radiation pattern. While compared with the traditional corrugated structure, the new structure has a better front-to-back ratio (F/B ratio). Properly chosen thickness and dielectric constant of substrate en...
متن کاملHigh Gain Broadband Plasmonic Slot Nano-Antenna
High gain broadband plasmonic slot nano-antenna has been considered. The theory of plasmonic slot nano-antenna (PSNA) has been developed. The analytical model takes into account also the electrical field inside the metal due to imperfectness of metal in optical range, as well as numerical investigation based on finite element method (FEM) has been realized. It should be mentioned that Yagi-Uda ...
