Cantennas became a huge hit because of simple construction and easy for a home user to make them. They are a big boost to the typical rubber finger antenna on many devices, providing 3x the power in a wanted direction.

Cantenna Yagi for WiFi

14.3 dBi

14.6 dBi

Cantennas became a huge hit because of simple construction and easy for a home user to make them. The simplicity is also limiting performance to around 7dBi. This cantenna is actually a Yagi in a can. A yagi works by taking that pin radiator such as in a normal cantenna and putting a bunch of parasitic elements in front of it precisely spaced that propel and direct the signal forward. This "cantenna" shows 3x more forward power than the normal cantenna. These are not easy to make at home.
