Design and analysis of wide wall slotted-waveguide array

This paper presented a Slotted-waveguide Array Antenna which is simulated using HFSS. HFSS is an electromagnetic simulate software which is invented by Ansoft. It can give the return loss and directivity of this Slotted-waveguide Array Antenna. First,the Slotted-waveguide Array Antenna will be designed according to waveguide theory,Slotted-waveguide Array Antenna and trapezoidal step-index. Then,Slotted-waveguide Array Antenna is simulated by using HFSS and manufactured Slotted-waveguide Array Antenna,At last,the antenna is measured and analysis the reason which effect the E-plane and H-plane radiation pattern. This paper gives a method to analysis Slotted-waveguide Array Antenna and has a important significance in project application.
