High-power microwave antennas have a great demand in defence technology and conical horn antenna is one of them. This antenna is known for producing symmetric beam radiation pattern, high directive gain. In the proposed work, we designed two conical horn antennas: one for a power of 200 MW over X-Band and the other for a power of 350 MW over C-Band. The electromagnetic simulation of the antennas is carried out using CST software. The results show return loss less than −20 dB, gain more than the required 10 dBi, cross polarization less than −20 dB, voltage standing wave ratio (VSWR) between 1 to 1.2, and side lobe level (SLL) less than −20 dB for both antennas.

摘要

High-power microwave antennas have a great demand in defence technology and conical horn antenna is one of them. This antenna is known for producing symmetric beam radiation pattern, high directive gain. In the proposed work, we designed two conical horn antennas: one for a power of 200 MW over X-Band and the other for a power of 350 MW over C-Band. The electromagnetic simulation of the antennas is carried out using CST software. The results show return loss less than −20 dB, gain more than the required 10 dBi, cross polarization less than −20 dB, voltage standing wave ratio (VSWR) between 1 to 1.2, and side lobe level (SLL) less than −20 dB for both antennas.
