Design of Controlled Radiation Pattern Antenna Based on Air-Ground Communication System

This paper proposes a controlled radiation pattern antenna (CRPA) system, which can be utilized in air-ground anti-jamming communication. A simple bent dipole antenna is proposed, capable of achieving effective transmission in vertical direction, with a 3-dB beamwidth of approximately -64° to 64° in the Z-axis direction. Moreover, it also ensures a certain level of transmission capability in the XoY plane. Subsequently, the proposed antenna array is combined with an adaptive anti-jamming algorithm to construct the CRPA system. Through testing, it is demonstrated that this system exhibits higher signal-to-interference ratio (SIR) and practicality compared to CRPA systems utilize traditional antenna arrays.
