Network, AntennaAbstract
All aspects of humans connect to devices and applications on wireless networks, such as connecting to computers for online study during the COVID-19 pandemic, connecting to tablets to watch movies, and connecting to mobile phones for financial transactions. These factors have driven the development of higher-performance wireless networks. However, the number of nodes is increasing rapidly. Therefore, the network cannot support all nodes as they use channels simultaneously. Moreover, the bandwidth of wireless networks is limited to a maximum value. So it is a good idea to optimize the wireless network at the lower layer. In the physical layer, the array antennas use to transmit and receive data. The beamforming of the array antenna can form a beam at all angles and connect the nodes from the source. This antenna uses the placement of the antenna elements to create the array pattern. Therefore, this is important for array patterns. In this paper, we analyze the impact of antenna elements on wireless networks based on 802.11 DCF. The indicators are communication links, throughput, and delay.
