Triangular Metamaterial Loaded Antenna for Low RCS Stealth Application
This work proposes a design of triangular metamaterial loaded antenna with low RCS, which can be employed for space research and stealth applications. Circular and upturned C-shaped resonating slots are introduced in the rectangular patch to aid in miniaturization and impedance matching respectively. The reduced RCS, triangular SRR and CSRR are entrenched on the top and ground plane respectively; these have the added advantage of a compact unit cell. The two radiating edges of the antenna are loaded with dual-section stepped impedance resonators to curb the reflection of the impinging signal. The proposed antenna resonates at 2.25 GHz with a reflection coefficient of −20.83dB. The gain of the antenna is 4.11dBi, which is typical of a low RCS radiator. The impedance bandwidth is 46.5MHz and the antenna has a low monostatic RCS of −23.796dBsm at the fundamental resonant frequency. Since the antenna has a low RCS at the resonance frequency, it can be utilized for defense and stealth applications.
