Abstract
The invention discloses a high-impedance-bandwidth microstrip antenna. The high-impedance-bandwidth microstrip antenna comprises a dielectric layer, a radiation patch and a microstrip feeder line which are formed on one surface of the dielectric layer, and a grounding part which is formed on the other surface of the dielectric layer, wherein the microstrip feeder line is positioned just above the grounding part; the radiation patch comprises a first rectangular radiation section and a second rectangular radiation section; the second radiation section is connected between the microstrip feeder line and the first radiation section; and a step part is formed between each of the two ends of the second radiation section and the first radiation section separately. According to the microstrip antenna, nicks are formed in the two top corners of the radiation patch, so that the impedance bandwidth can be greatly improved; and in addition, due to an inclined top corner of the grounding part, smooth transition from one resonance mode to another resonance mode can be achieved, so that relatively high impedance matching and wide-frequency-range gain stability can be achieved.
