Types and Application Analysis of Wi-Fi Antennas | TengXiang Antenna| TengXiang Antenna

Omnidirectional antennas radiate signals evenly in a 360° horizontal direction, spreading wireless signals all around with the antenna as the center to achieve wide regional coverage. Commonly used in homes and small offices, it can be placed at a central position to provide stable signal access for surrounding smart devices such as mobile phones, tablets and smart home appliances. Nevertheless, omnidirectional antennas have relatively low gain, usually ranging from 2dBi to 5dBi. Since signals need to be evenly distributed in all directions, the signal strength cannot be maximized in a single specific direction.

Different from omnidirectional models, directional antennas concentrate signal transmission and reception in a fixed narrow angle, generally controlled within 60° to 120°, with a high gain of about 10dBi to 20dBi. With signal energy focused in one direction, it achieves longer transmission distance and stronger signal strength along the pointing direction. This type of antenna is widely used for long-distance Wi-Fi transmission. For instance, when establishing Wi-Fi connection between two buildings, directional antennas can realize stable signal transmission and reduce unnecessary signal loss in other directions. Meanwhile, the high-gain directional antennas launched by TengXiang Antenna are also ideal choices for outdoor wireless monitoring systems, ensuring continuous and stable signal transmission for surveillance cameras.
