Example Embodiment
[0047] Example one
[0048] Please refer to figure 1 with figure 2 The embodiment of the present invention provides a broadband reconfigurable dielectric resonator antenna, including: a dielectric substrate 1 and a dielectric resonator 2 arranged at the center of the antenna; the circuit is mainly arranged on the first surface 101 of the dielectric substrate 1. And on the second surface 102 opposite to the first surface 101.
[0049] (1) The circuit structure of the first surface 101 of the dielectric substrate 1
[0050] Please refer to figure 1 with image 3 , The first surface 101 of the dielectric substrate 1 is provided with a metal ground layer 11;
[0051] The metal ground layer 11 is etched with a cross seam structure 3; the cross seam structure 3 is composed of a first cross groove 31 and a second cross groove 32 of the same size that cross vertically;
[0052] The dielectric resonator 2 is arranged close to the first surface 101 and is located directly above the cross slit s...
