Abstract
A phased array antenna panel includes an array of antenna cells. Optionally, the phased array antenna panel includes a frame with multiple shielding fences housing the array of antenna cells. Each antenna cell includes a raised antenna patch with air dielectric. In one example, the raised antenna patch may include four projections having outwardly increasing widths, and four supporting legs, each of the four supporting legs situated between a pair of adjacent projections. A first differential feed port may be coupled to first and second supporting legs of the raised antenna patch through first and second transformers, and a second differential feed port may be coupled to third and fourth supporting legs of the raised antenna patch through third and fourth transformers. A return loss in a frequency range of between 27.5 GHz and 29.5 GHz of each antenna cell is less than about −10 dB.
