Ku Band

Broadband slotted circular patch antenna with Defective Ground Structure intended for Ku band satellite communications is presented in this communication. The proposed antenna has a fundamental circular radiating element in which a square ring slot is etched along with a circular slot inside it. The ground is etched with a rhombus ring slot at the center and square slots in the corners. The defective ground provides multiple frequencies of operation and the slots in the radiating element act as filters combining the multiple frequencies of operation into broadband. The antenna is fabricated on an FR4 substrate with a volume of 40mm×48mm×1.59mm and a dielectric constant of 4.4. The antenna has been excited using a stripline feed of 50Ω impedance. The proposed antenna has an impedance bandwidth of 1.87GHz ranging from 13.61GHz to 15.48GHz with gain and directivity of 2.2dB and 6.09dB at 13.84GHz, 2.8dB and 5.47dB at 14.48GHz, respectively. The simulated and measured antenna results are in good agreement, showing that the proposed techniques enhance the antenna bandwidth.

Ku Band

A low VSWR and high efficiency antenna array operating in the Ku band for satellite communications is presented in this paper. To achieve high radiation efficiency and broad enough bandwidth, all-metal radiation elements and full-corporate waveguide feeding network are employed. As the general milling method is used in the multilayer antenna array fabrication, the E-plane waveguide feeding network is adopted here to suppress the wave leakage caused by the imperfect connectivity between adjacent layers. A 4 × 8 elements array prototype was fabricated and tested for verification. The measured results of proposed antenna array show bandwidth of 6.9% (13.9–14.8 GHz) for VSWR < 1.5. Furthermore, antenna gain and efficiency of higher than 22.2 dBi and 80% are also exhibited, respectively.
