Design of a MIMO antenna for high throughput WLAN applications

Abstract

In this paper, a novel multiple-input-multiple-output tri-band antenna with a featured embedded common mode (CM) choke is presented to prevent receiver desense and improve throughput for WLAN applications. The proposed antenna design consists of two wide-bandwidth high-efficiency electromagnetic structure elements with an Γ-shaped branch and an open-ended slot line in the element. The Γ-shaped branch is used to reduce the size of the antenna element. The open-ended slot line is a balun, which is used to reduce the CM current on the coaxial cable. The proposed antenna was simulated and measured, and the simulated results agree well with the measured ones. The results have also demonstrated that the proposed antenna is well suited for WLAN applications as it covers the three operating bands of 2.4G, 5.2G and 5.8G.

A compact quasi‐omnidirectional slot antenna for Wi‐Fi 6E application

“…The slot antennas have been reported to meet the requirement of Wi-Fi 5 [8][9][10] attributed to the advantages of high radiation efficiency and flexibility. To satisfy the demand for Wi-Fi 6E application, a compact slot antenna is proposed in this letter.…”

Design of quad‐element MIMO antenna with a multi‐functional ground topology for UWB wireless applications

“…Indoor/outdoor applications needs communication devices wih higher bandwidth, higher throughput and efficient radio wave propagations in scattered/multipath environments (practically considering scenarios like HD video streaming, stadium environments, suburban neighborhoods, high conectivity broadbands to homes and bussiness enterprises). In such communication scenarios, MIMO antennas are highly required to meet the end‐user requirements 1,2 . As per Shannon's theorem, more number of N ‐antenna elements increases the channel capacity of the system and also enhances the bandwidth potential.…”
