The effects of four coupling slots on antenna resonance frequency and bandwidth are studied respectively. And these effects are explained with the near field distributions. Feeding characteristics of several coupling slots are analyzed and compared, which greatly improve the flexibility of antenna design. By modifying the feeding device with the conversion idea, a broadband microstrip antenna is designed with a bandwidth of 28.9% .The gain is more than 8dBi in the operating frequency band of 3.76~4.80GHz. The gain bandwidth is 24.2%.
