Firstly, a unified numerical calculation formula for solving the antenna current distribution and radiation field is given. Then the shape of the loop antenna printed on different dielectric substrates is analyzed by changing the shape parameters of the hyperbolic curves. The result shows that the resonance resistance matching with the feeder can be obtained by adjusting the geometry of the loop antenna.
