WiFi antennas serve as devices to receive and transmit wireless network signals. They establish connections with wireless routers or base stations and deliver these wireless signals to network devices. WiFi antennas are typically used in conjunction with devices like laptops, smartphones, and tablets to enhance their network connection speed and stability.

1. Characteristics of WiFi Antennas
   WiFi antennas exhibit distinct features such as frequency response relative to the center frequency, high gain, strong directionality, good interference resistance, and adjustable operating frequency bands and polarization modes.

2. Types of WiFi Antennas
   WiFi antennas come in various types, including built-in, external, omnidirectional, directional, and MIMO antennas, offering different advantages and applications.

3. Function of WiFi Antennas
   The primary role of WiFi antennas is to extend and enhance WiFi signals, facilitating faster and more stable network connection speeds. They aid users in transmitting and receiving network signals over longer distances, improving the quality and efficiency of data transmission. Furthermore, the use of WiFi antennas in complex wireless environments effectively reduces signal interference.
