Preliminary Study on Triple-Resonant, Low-profile High Gain Stacked Circular Sector Patch Antenna

Preliminary studies of high gain, wideband triple-resonant patch antenna are advanced. Two circular sector radiators which flared angles are different can be properly stacked, thus leads to wideband, dual-mode and low-profile characteristic. Then, the first high order resonant mode within the upper patch radiator is excited and perturbed to generate a triple-resonant characteristic. In simulation, the proposed antenna exhibits a usable bandwidth of 12.3% and the boresight gain up to 11dBi. Meanwhile, the profile can be controlled less than 0.043-guided wavelength.
