A Ku-band satellite application-based printed planar array is conferred in this article. The proposed array's sole radiator design is inspired by the essence and based on a nature-inspired flower. The solitary element offers enormous directivity and insignificant cross-polarization (x-pol.) level in the half-power beamwidth (HPBW) portion of the main beam's path. Networks within the array are built to have low loss and fast bandwidth response times for the corporate feed network. The sole antenna has a very high gain and a substantial impedance bandwidth of 11.52 dBi and 528 MHz, respectively, and resonates at 17.96 GHz. The array produces 16.83 dBi gain and 764 MHz impedance bandwidth at the resonant frequency of 17.97 GHz. In the direction of the primary beam's propagation, the prototyped array delivered À42 dB of measured x-pol. level. For evaluating the prototypes' electromagnetic compatibility (EMC), the derived correction factors (CF) are 42.54 and 39.56 dB/m, respectively. In addition, the proposed prototypes have good radiation efficiency of 92% and 90%, respectively. The measured result of the prototype is quite comparable to that of its modeled equivalent.

This article presents a 2 × 2 printed planar array and its single element for weather‐monitoring (8.175–8.125 GHz) related applications. The proposed array's single antenna prototype is a nature‐inspired‐based design and is derived from natural Clover‐leaves. The single proposed element gives an appreciably decent gain and heavily suppresses cross‐polarization (x‐pol.) along its main beam direction. The array is designed using the Wilkinson divider‐based corporate feed network to achieve a low loss level and better bandwidth response. The sole fabricated element resonates at 8.19 GHz and offers 7.85 dBi peak gain and 336 MHz impedance bandwidth, respectively. Similarly, 12.30 dBi gain and 263 MHz impedance bandwidth have been achieved from the array geometry at the resonating frequency of 8.195 GHz. The prototypes' computed correction factor is 40.64 and 36.20 dB/m, respectively. Both the prototypes provide 100% bandwidth coverage for weather‐monitoring applications under X‐band. Both the prototypes provide a below −35 dB x‐pol. Along its main beam direction. They offer reasonably good radiation efficiency of 92.77% and 89.16%, respectively. An excellent agreement has been entrenched in between measured and simulated results of the prototypes.

Summary This article presents a four‐elements linear array of highly directive radiators for Ku‐band satellite applications. The antenna array's sole element is a newly introduced nature‐inspired Night‐flowering Jasmine‐shaped radiator. The proposed single element gives an appreciably decent gain and shallow cross‐polarization (x‐pol.) level along its main beam direction. The array's corporate feed network is designed in a precise manner to achieve a low level of loss and better bandwidth response. The fabricated sole antenna resonates at 17.95 GHz and offers a peak‐gain and return‐loss bandwidth of 11.54 dBi and 537 MHz, respectively. Similarly, 16.69 dBi absolute gain and 756‐MHz bandwidth have been achieved from the array geometry at 17.96 GHz resonating frequency. The prototypes' electromagnetic compatibility (EMC) is validated by their computed correction factor (CF) values, and those are becoming 43.73 and 38.57 dB/m, respectively. The measured cross‐pol. of both prototypes, along the entire HPBW region, is below −35 dB. The prototypes offer a reasonably good radiation efficiency of 92.09% and 97.25%, respectively. Both the prototype's measured results make an excellent agreement with the simulated outcomes.
