As IoT continues gaining wider acceptance in the market with extensive connection between all kinds of devices and cloud-based servers, WiFi routers or wireless set-top-box (STB) are becoming the critical devices to establish an efficient way to build reliable and secure connectivity. The next generation of the Wi-Fi standard is Wi-Fi 6, also known as 802.11ax, with the further advancement of WiFi 6E. This standard was built based on the well-established foundation of 802.11ac while adding efficiency, flexibility, and scalability allowing new and existing networks to improve data transmission speed and capacity for next-generation applications. Successful implementation of Wi-Fi 6E requires a higher degree of integration between devices, access points, and other parts of the system because every part of the system requires seamless integration. The tighter radio frequency (RF) specifications of the Wi-Fi 6E means that every aspect of the RF system design as well as antenna optimization becomes more complicated. Due to the increased complexity and demands on the performance of Wi-Fi 6E, antennas must meet these stringent requirements to achieve best performance.
