| Abstract: | Feeding method for mierostrip antenna has great influence on the characteristic impedance matching. According to the features,based on the model of microstrip line side-fed, plug-in feed based of multimode cavity model was introduced. The method is applied to the microstrip array antenna model, the antenna gain and directiviey are effectively proved. The HFSS simulation results prove that the improved methods for the antenna directivity and gain are increased, the impedance matching is better. |
