Abstract:
A kind of microstrip array double-antenna (MADA) and its corresponding radar front-end are presented in this paper. The double-antenna comprises two individual 4-patch arrays which are coplanar in a round substrate with 25mm diameter and are used as receiver antenna and transmitter antenna respectively in 36 GHz radar front-end. Both simulation and test results of the antenna are exhibited, which shows better isolation between two arrays below −42 dB in a wide band. Test results of radar front-end with MADA are also presented, from which we can see perfect performance the system has. With improvement of radar system, a more compact MADA with 18.6mm diameter is designed, fabricated and measured, which shows a good response.
