Abstract
Described and disclosed herein is a wideband polarized patch antenna and the antenna array that can cover mmWave frequency band from 24.3 to 29.6 GHz for 5G applications, and a feeding structure for such an antenna comprising a single element of a polarized helical-shaped L-probe fed patch antenna (HLF-PA) package.
Claims27
A polarized helical-shaped L-probe fed patch antenna comprising:
- a substrate;
- a copper-clad laminates (CCL) layer;
- a plurality of layers of prepregs (PPG), wherein a portion of the plurality of layers are below the CCL layer and a portion of the plurality of layers of PPG are above the CCL;
- a plurality of metal layers, wherein a portion of the plurality of metal layers are below the CCL layer and a portion of the plurality of metal layers are above the CCL and wherein each metal layer is sandwiched between two PPG layers, between a PPG layer and the CCL layer, between the substrate and a PPG layer, or on top of a PPG layer,
- wherein the CCL, the portion of the plurality of layers of PPG that are above the CCL, and the portion of the metal (TM) layers above the CCL comprise a patch antenna structure and the portion of the plurality of layers of PPG, and the portion of the metal (BM) layers below the CCL comprise feeding lines;
- a patch radiator located on a top metal layer;
- one or more helical-shaped L-probe feeding structures, wherein each structure comprises a vertical component having a helical winding structure, a horizontal component, and one or more coaxial-like feeding line structures.
