A balanced patched inverse F antenna comprises a radiation conductor and a balun circuit. The radiation conductor includes a main body, a first branch and a second branch. The balun circuit includes an unbalanced port, a balanced port, and first, second, third and fourth components, with the first, second, third and fourth components being serially connected. A feeding input of the unbalanced port is connected to the second and third components, a grounding wire of the unbalanced port is connected to the first and fourth components, an inverting terminal of the balanced port is connected to the first and second components, a non-inverting terminal of the balanced port is connected to the third and fourth components, and the inverting and non-inverting terminals are respectively connected to the first and second branches.
