Abstract
The utility model discloses a kind of cableless phase shifter and antenna, by dividing cavity into first cavity and second cavity, and using electromagnetic isolation component to carry out physical and electromagnetic isolation to two functional areas, effectively inhibit the mode resonance phenomenon generated in 3.3GHz~3.8GHz frequency band due to cavity size is too large, based on reducing the loss brought by mode resonance phenomenon, to improve the electrical performance stability of entire phase shifter.In addition, by controlling the width and height of the first cavity, and combining the dielectric material, electromagnetic characteristic parameters and PCB structure, the lowest resonant frequency of the cavity is improved to the target level (greater than 3.91GHz), thereby avoiding the working frequency range, significantly enhancing the compatibility and flexibility of the overall design under different frequency bands.
