Abstract
An antenna architecture with a dual-band patch antenna structure having a broadened low-frequency beamwidth is disclosed. The dual band antenna structure comprises a high frequency patch antenna cavity stacked inline above a low frequency patch antenna cavity. An N-shaped metallic wall surrounds the low frequency patch antenna cavity and broadens the emission radiation beamwidth of the low frequency emission. As such, these dual band antenna structures can emit radiation with a beamwidth of approximately 90 degrees in the low frequency band of 700 MHz to 900 MHz as well as the high frequency band of 1.7 GHz to 2.2 GHz.
