Abstract:
1. A grounded self-complementary antenna for elevating a radio signal transmission effect of an electronic device comprising: a metal radiator used for responding to a plurality of electromagnetic waves in a wavelength range; a metal complementary element being disposed adjacent to said metal radiator, and having an open zone being disposed at an inner portion thereof; and a metal grounding element disposed at said electronic device; wherein said metal radiator has a specific shape and said open zone has a shape corresponding to said metal radiator to allow said metal radiator and said metal complementary element to form a self-complementary antenna; one end of said metal radiator, which is adjacent to said metal complementary element, has a feeding point for transmitting electromagnetic signals; said metal grounding element contacts and electrically connects with said metal complementary element for substantially enlarging an area of a grounding end of said self-complementary antenna; a first insulation material layer is disposed for said metal radiator being capable of not contacting with said metal grounding element; said metal complementary element and said metal grounding element contact with each other with a second insulation material layer being disposed for edges of said open zone being capable of not contacting with said metal grounding element.
