A Wideband Cylindrically Conformal Patch Antenna Array with 3D Printed Substrate

A wideband cylindrically conformal patch antenna array is presented. The quarter cylindrical substrate is realized by 3D printing technology with material of acrylonitrile butadiene styrene (ABS). The main highlight of this proposed structure is that the SMP sockets and antenna substrate are designed and fabricated simultaneously. This proposed 3D printed antenna is capable of covering 8.37 GHz~11.l GHz (active VSWR≤2). In addition, a 10 × 10 quarter cylindrically conformal array is also simulated. This proposed array achieves low cross polarization within the operating band and its simulated gain and radiation efficiency are about 21.6 dBi~24.7 dBi and 77%~97%, respectively.
