Simultaneous Transmit and Receive Antenna System

This technology operates in the domain of wireless communication, where there's a growing demand for efficient and rapid data transmission. As the shift becomes more toward a digital world, having solid wireless connections becomes increasingly critical. The demand for high-performance antenna systems capable of seamless and simultaneous transmission and reception is growing. One pressing concern in wireless communication involves interference and isolation, primarily when antennas operate in close proximity. The challenge of producing a robust simultaneous transmit and receive antenna system lies in maintaining high isolation between transmitting and receiving elements, reducing interference and enhancing transmission quality. This problem has posed a significant obstacle to the progress of advancing wireless communication technologies.

Technology Description

The technology is a simultaneous transmit and receive antenna system comprising a ring array either filled with transmit antenna elements or receive elements. A separate antenna element lies on an axis that passes through the center of the ring array and is perpendicular to it. In each configuration, the antenna elements opposite each other in the ring array possess a phase difference of 180° to create a radiation pattern null at the antenna on the axis running through the center of the array. This arrangement ensures high interference isolation. Its unique construction allows for a high degree of isolation between the transmit and receive elements, achieved by having at least one ground plane and an electrically conductive cylinder positioned on the perpendicular axis inside the ring array. This advanced configuration allows the system to be compatible for wireless data transmission following well-known wireless communication standards, such as WIFI IEEE standard 802.11 or WIMAX IEEE standard 802.16.
