摘要
Abstract
The planar bow-tie antenna employing the form of dielectric embedded is buried in the sub-strate. A tapered planar microstrip balun is designed so as to achieve transforming unbalance to balance. In order to realize impedance matching,the structure of triangular microstrip balun with microstrip transmis-sion line is designed. The designed antenna is simulated and optimized by Ansoft HFSS and compared with fabricated physical object. Simulated and measured results show that the relative bandwidth reaches 88. 7%,while the measurement is 79. 3%,which has the ultra-wideband(UWB) characteristics. At the working central frequency,the gain is up to 6. 9 dB,while the measurement is 5. 8 dB,which meets the need of a certain project and can be applied in the receiving and transmitting antenna of ground penetrating radar system.关键词
