| Abstract: | To study the slot-coupled patch antenna,a physical model of antenna is set up by using HFSS simulation,and some results such as return loss and voltage standing wave ratio(VSWR) are obtained.As the size of the slot is optimized,the performance of antenna has been greatly improved,including the follows: increasing the values of return loss and voltage standing wave ratio at the center operating frequency;increasing the frequency bandwidths;increasing the level of the antenna gain. |
