A circularly polarized curved surface array antenna with high gain is presented. The array, which can perform circular polarization operation, is constructed on a cured plane.The measured 10dB return loss (RL) bandwidth is 15 % (5.25 to 6.1 GHz), and the measured 3dB AR bandwidth is 53% (5.4 to 8.4GHz). Not only does the proposed antenna feature broadband operation, but it also possesses high-gain characteristic. The antenna gain is significantly enhanced to 20 dBic by the introducing of the multiple array.

A dual-polarized X-band conformal array antenna is presented for unmanned aerial vehicles with polarimetric radars/sensors. Starting from the planar structure, the array antenna consisted of sixteen 2 Â 2 subarrays is conformal to the cylinders with various curvature radii to fit the payload box of the airborne vehicle. The return losses are almost constant even if the curvature radius changes. Measured radiation patterns are compared with various curvatures at the same frequencies. The array can be easily placed on the aircraft payload or fuselage due to its ultra thin thickness, ultra lightweight, and conformal structure, which has potential airborne applications in polarimetric radar surveillance, remote sensing, and wireless communications.

“…Zhang et al [6] combined a shorted bowtie dipole and an L-shaped electric dipole fed with -shaped feed strip to achieve wideband performance in a compact design. Other researchers [7] have recently presented a wideband slot-loaded octagon patch capacitively fed by a small rectangular patch for use on cylindrical surfaces. Stacked patches are often implemented in LTCC antenna design to achieve wide bandwidth [3], [4], [8]- [10].…”

This letter presents a wideband patch antenna on a low-temperature cofired ceramic substrate for Local Multipoint Distribution Service band applications. Conventional rectangular patch antennas have a narrow bandwidth. The proposed via-wall structure enhances the electric field coupling between the stacked patches to achieve wideband characteristics. We designed sameside and opposite-side feeding configurations and report on the fabrication of an experimental 28-GHz antenna used to validate the design concept. Measurements correlate well with the simulation results, achieving a 10-dB impedance bandwidth of 25.4% (23.4-30.2 GHz). Index Terms-Local Multipoint Distribution Service (LMDS)antenna, low-temperature cofired ceramic (LTCC) patch antenna, stacked patch, via-wall structure, wideband patch antenna.
