N2 - High order harmonic may affect antenna performance, reduce antenna efficiency and cause electromagnetic interference. So suppression of the harmonic has been a focus issue in the field of antenna design. It is demonstrated that the photonic band gap (PBG) structure and defect ground structure (DGS) provide an effective way for suppressing high order harmonics of antenna. In this paper, a novel antenna with wideband high order harmonic is presented by using the proposed complementary opening defected microstrip structure (CODMS). The proposed structure cell with great advantages in the miniaturization of the antenna contains two fundamental resonant frequencies which can be tuned by adjusting the geometry parameters. First, the influence of CODMS cell parameters on the band-stop is examined in order to obtain design rule for the harmonic suppression. Second, two CODMS cells with different size in a novel configuration is developed in order to control harmonics of the rectangular patch microstrip antenna with the fundamental frequency at 1.5 GHz. By elaborately designing the structure parameters, four band-stops are achieved which match the four high order harmonics of the antenna well. Then, the patch antennas with the proposed CODMS are implemented with the conventional patch antenna without the CODMS as a reference. The simulated results show that the reflection coefficient from the second to the fourth harmonics has been effectively suppressed over 3 dB without affecting the fundamental frequency and the maximum inhibition effect appears at the second harmonic reaching 9.2 dB. The co-polarized and cross-polarized fields at the fundamental frequency of the presented antenna have little discrepancy with the reference antenna while the radiation pattern at the high order harmonics is suppressed about 15 dB in both E-plane and H-plane. Thus, the presented antenna has superiority in suppressing wideband high-order harmonics with compact size, which also maintains the integrity of the ground plane, making it easier to integrate with microwave circuit for wireless applications.
