Design of Log-periodic Slot Antenna Array with Novel Cavity |
| |
| Abstract: | A Log-periodic Slot Antenna with novel cavity is introduced,various parameters are analyzed. A 9×7 log-periodic slot antenna array based on this novel element.Antenna array is designed by HFSS13.The simulated result shows that the antenna array operates in 1.5 GHz~6 GHz.Within the band,return loss is below 3,VSWR is below -10 dB,the antenna gain is upper than 20 dBi and the maxim gain is 29.6 dBi.The antenna array has good unidirectional radiation patterns,which makes the antenna array suitable for the application in UWB radar and detection. |
