PURPOSE: To easily install an antenna by providing a slot on a metallic pipe being an outer conductor, inserting one end of the metallic pipe into a sleeve for the connection of an F plug connector and mounting and fixing a center conductor to a center conductor holding part arranged in ...
Provided are a microstrip stack patch antenna using multilayered metallic disk array and a planar array antenna using the same. The microstrip stack patch antenna of the present research concentrates beam patterns and acquires a high gain characteristic by finitely depositing metallic disks in a bore...
Here we show a highly sensitive and selective detection method for the discrimination of carbohydrate molecules using nano-slot-antenna array-based sensing chips which operate in the terahertz (THz) frequency range (0.5-2.5 THz). This ... Lee, Dong-Kyu,Kang, Ji-Hun,Lee, Jun-Seok,... - ...
The assembly is fitted along a pole P or a wall at a desired position in a perpendicular direction, and the connector of plug structure is used to connect a coaxial cable 30 to an F plug connector 17 installed to the connector 14 of each metallic pipe slot array antenna 10. A high ...
metallic post-array loaded cylindrical dielectric resonator antennaAn investigation of a novel cylindrical dielectric resonator antenna (DRA) configuration has been carried out. It is shown that two resonances including the full- and half-cylindrical HE11δ-like modes can coexist simultaneously at ...
Then, a 1 × 8 antenna array is designed, fabricated, and measured. The measured results demonstrated that the impedance bandwidth and 3-dB AR bandwidth of the proposed 1 × 8 array are 14.8% (41.9–48.6 GHz) and 11% (43–48 GHz), respectively. The measured peak gain of the 1 × ...
A miniaturized and closely packed eight element annular ring multiple-input multiple- output (MIMO) antenna array is designed to operate from the 3 to 6 GHz band for 5G smartphone applications. In MIMO, the orthogonally placed antenna pairs maintain high isolation. The proposed ...
This work is aimed at designing an optical nano-antenna structure to enhance the optical absorption in 1.0-1.7 渭m and improve the performance of InP-based InGaAs sensors. We report comprehensive analysis of an optical nano-antenna structure of metallic ball array for surface plasmon enhancement ...
A spiral Radial Line Slot Array antenna without dielectric loading or slow-wave material was designed for deep space applications. Metallic and Dielectric standoffs are investigated to separate the slotted plate from the ground plane. The antenna was designed for the X-band Deep Space Network (DSN...
The measured broadside gain of the proposed antenna array with grooves is 13.59 dBi. Compared to a conventional SIW cavity‐backed slot antenna array, the proposed antenna array with 16 grooves has an enhanced gain of 5.6 dB.doi:10.1002/mop.32139Youngtaek Hong...
