Abstract :
This paper presents a modified printed monofilar square spiral antenna operates at Ka band frequencies. Different from the conventional monofilar square spiral, three stubs are introduced to improve the impedance matching and axial ratio bandwidth. Simulation results show that the presented antenna has 18.2% 10-dB return loss and 11.8% 3-dB axial ratio bandwidth.
