A Broadband Magnetoelectric Dipole Reflectarray Antenna at Ku-Band
In this letter, a broadband reflectarray (RA) antenna operating at Ku-band is proposed for wireless communication systems. Because the magnetoelectric (ME) dipole antennas have excellent low profile and wide impedance bandwidth performance, a multilayer wideband element is proposed based on a ME dipole and a true-time delay line. In addition, the elements achieve smooth and linear phase shift curves while maintaining high reflection amplitude over the operating frequency range. Next, employing the above element, a broadband linearly polarized RA antenna with a square aperture is designed and fabricated. The measured results show that the peak gain of the proposed antenna is 27.2 dBi, and the aperture efficiency is 45.3%. Besides, the 1 dB gain bandwidth is 27.5% from 14.4 to 18.8 GHz. The proposed RA antenna has the potential for broadband applications in wireless communication systems.
