Definition and Significance of RECTENNA: INSET-FED AND EDGE-FED PATCH ANTENNAS WITH
RECTENNA refers to a rectifying antenna system that integrates patch antennas with rectifying circuits to convert microwave energy into usable direct current (DC) power. The system primarily operates at a frequency of 2.45 GHz. The main designs, inset-fed and edge-fed patch antennas, are critical for efficient wireless power transmission.
The inset-fed design involves a notch in the patch, which controls the matching and bandwidth of the antenna. The edge-fed design is simpler but can suffer from broader bandwidths and additional matching challenges. Both designs are pivotal due to their applications in wireless communication, especially in environments that require low profile and efficient energy conversion systems.
