What is claimed is: 1. A power divider circuit using a mutual inductance, comprising: a first primary inducing element having a first terminal connected with a first output port and a second terminal connected with a second primary inducing element; the second primary inducing element having a first terminal connected with a second output port and a second terminal connected with the first primary inducing element and magnetically and mutually coupled with the first primary inducing element; a first sub inducing element having a first terminal connected with an input port and a second terminal connected with the second terminal of the first primary inducing element and the second terminal of the second primary inducing element; and an isolation network connected between the first output port and the second output port, wherein the first sub inducing element is magnetically and mutually coupled with each of the first primary inducing element and the second primary inducing element. 2. The power divider circuit of claim 1 , further comprising an input matching network having a first terminal connected with the input port and the first terminal of the first sub inducing element and a second terminal connected to ground. 3. The power divider circuit of claim 1 , further comprising a wideband network having a first terminal connected with the second terminal of the first primary inducing element and the second terminal of the second primary inducing element and a second terminal connected to ground. 4. The power divider circuit of claim 1 , wherein the first primary inducing element, the second primary inducing element, and the first sub inducing element are an inductor or a transmission line. 5. The power divider circuit of claim 1 , further comprising a third primary inducing element having a first terminal connected with a third output port and a second terminal connected with the second terminal of the first primary inducing element and the second terminal of the second primary inducing element and magnetically and mutually coupled with the second primary inducing element, wherein the first sub inducing element is magnetically and mutually coupled with the third primary inducing element. 6. The power divider circuit of claim 1 , further comprising: a third primary inducing element having a first terminal connected with a third output port and a second terminal connected with a fourth primary inducing element; the fourth primary inducing element having a first terminal connected with a fourth output port and a second terminal connected with the third primary inducing element and magnetically and mutually coupled with the third primary inducing element; and a second sub inducing element having a first terminal connected with an input port and a second terminal connected with the second terminal of the third primary inducing element and the second terminal of the fourth primary inducing element, wherein the second sub inducing element is magnetically and mutually coupled with each of the third primary inducing element and the fourth primary inducing element. 7. The power divider circuit of claim 6 , further comprising another isolation network having a first terminal connected with the first terminal of the second primary inducing element and a second terminal connected with the first terminal of the third primary inducing element. 8.
