Wi-Fi antennas are devices that transmit and receive wireless signals, allowing electronic devices to connect to the internet without cables. They come in various shapes and sizes, including internal antennas found in laptops and external antennas used in routers. The design and placement of these antennas can significantly affect the strength and range of the Wi-Fi signal. There are two main types of Wi-Fi antennas: omnidirectional and directional. Omnidirectional antennas send signals in all directions, making them ideal for general coverage in homes. Directional antennas focus the signal in a specific direction, which can enhance performance over longer distances or in specific areas.
