Abstract:
1. An antenna structure for coupling electromagnetic energy between a chip and an off-chip element, comprising: a first resonant structure disposed on or in said chip, said first resonant structure configured to have a first resonant frequency; and a second resonant structure disposed on or in said off-chip element, said second resonant structure configured to have a second resonant frequency substantially the same as said first resonant frequency, said first resonant structure and said second resonant structure being mutually disposed within a near field distance of each other to form a coupled antenna structure configured to couple electromagnetic energy between said chip and said off-chip element, said electromagnetic energy having a selected wavelength in a wavelength range from microwave to sub-millimeter wave; at least a selected one of said first resonant structure and said second resonant structure comprises a resonant loop and a resonant capacitance.
