Embodiment Construction
[0016] The embodiment of the present invention provides a mobile phone antenna and a mobile phone, based on the principle of the echo characteristics of the double negative medium to reduce the resonant frequency of the antenna, so as to achieve the purpose of reducing the size of the mobile phone antenna. The mobile phone antenna adds a double-negative material metal layer on the metal floor under the dielectric substrate. The metal layer adopts a compact structure, and the size of each unit can be much smaller than the working wavelength of the antenna. The double negative material resonant cavity is formed between the double negative material, the conductive patch and the dielectric substrate. The double negative material resonant cavity plays a role of phase compensation for the inherent double positive material resonant cavity of the dielectric substrate, and the double negative material (DNG) resonant The cavity and the double positive material (DPS) resonant cavity are a...
