Novel triangular patch antenna with reduced radar cross section

A novel triangular patch antenna of decreased RCS is proposed and investigated for ultra-wide band (UWB) applications. The intention of antenna innovation is to realize radar cross section reduction. The patch slotted and miniaturization techniques are used. A radiating patch is innovated to improve RCS while two slots are notched on patch to maintain good radiation performance and enhance impedance matching of designed antenna. The RCS function of novel antenna is analyzed and matched with a referred patch. It is shown from outcomes that the new patch has an improved RCS in almost all the functioning frequency of 2-12GHz and gain has some reasonable incoherence in the wide band frequency. The simulated results demonstrate that the designed antenna offers good prospect for low RCS antenna applications.
