Understanding the U-Slot Antenna

A U-slot antenna, fundamentally a variation of the microstrip patch antenna, is characterized by the introduction of a U-shaped slot etched into the radiating patch. This modification is not merely aesthetic; it meticulously alters the antenna's electromagnetic field distribution, leading to enhanced performance characteristics. The primary advantages of incorporating a U-shaped slot include a significant increase in impedance bandwidth, often achieving around 30%, and the ability to facilitate multi-band operations.
