Abstract

Coastal Suveillance Radar (CSR) is crucial for coastal navigation. A microstrip rectangular patch with slotted inset-line antenna is proposed in this paper. The antenna operates at the frequency 9.37-9.43 GHz with VSWR below 1.3 and printed on Epoxy FR-4 substrate of dielectric constant of 4.6. The antenna array is also simulated on CST using uniform microstip array configuration consisting of 6×120 elements to yield the specification of horizontal beamwidth ≤ 1◦, vertical beamwidth ≤20◦, gain ≥30 dB and sidelobe level ≤ −27 dB. The simulation result of the array antenna has a horizontal beamwidth of 0.4◦, vertical beamwidth of 14.2◦, gain of 30.8 dB, and sidelobe level of −27.5 dB. Hence the proposed array antenna configuration is suitable for CSR application.
