APPLICATION OF A CYLINDRICAL ELECTROMAGNETIC BANDGAP STRUCTURE IN GAIN ENHANCEMENT OF A MICROSTRIP PATCH ANTENNA
摘要
Abstract
A new cylindrical electromagnetic bandgap (EBG) structure is introduced for improving the performance of a circu- lar micmstrip patch antenna. It is composed of two periodic structures with different periods. One is made of metallic rings and the other of grounding vias, which form a radically and circularly periodic structure. Firstly, a ordinary circular microstrip patch antenna is designed. Then, the parameter of the two periodic structures is analyzed by using simulation soft HFSS. Finally, the radiating pattern and the return loss of the microstrip antenna with EBG are compared with that of the one without EBG. In conclusion, based on the good impedance matching, an enhancement of the gain of about 4.6dB is obtained, which extends the application of these antenna.关键词
