“…If more degrees of freedom in design are introduced, that is, a bent dipole or an offset‐fed bent dipole, more resonant modes (including the even‐order ones) can be excited and employed to broaden the operation bandwidth, simultaneously realize dual‐band and wideband characteristics. Very recently, the proposed stub‐loaded technique has been further extended to design wideband quasi‐Yagi antennas and wideband dipole antenna with ultra‐wideband harmonic suppression characteristics …”

A survey of multi‐resonant antennas is comprehensively presented, with emphasis on theoretical framework, design approaches, and practical examples. This article begins with a brief history of the multi‐resonant dipole theory, and then concentrates on the design approaches that have been developed to typical, basic antenna elements, for example, electric dipole antenna, slotline antenna, loop antenna, complementary dipole antenna, and microstrip patch antenna. Design examples for different practical applications are then raised. In final, the multi‐resonant antenna design approach is summarized and compared to some relevant antenna design techniques.

“…However, the microstrip transmission line needs to pass through the ferrite cores, which greatly increases the difficulty of production. The singly‐polarized antennas have wide harmonic suppression bandwidth, but they cannot be extended for dual‐polarization easily. Compared with the above techniques, the method of combining filter circuits with antennas is a good choice to realized harmonic suppression due to their simple structure and high integration .…”

A dual‐polarized filtering antenna (DPFA) with high‐order harmonics suppression for 690‐960 MHz based station applications is proposed in this letter. The proposed DPFA is obtained by integrating a miniaturized lowpass filter with a ±45° dual‐polarized antenna (DPA) which made by two crossed dipoles. With the miniaturized lowpass filter, harmonic suppression is easily achieved by the proposed DPFA without increase its size. The experimental results which agree with the computer simulations show that wide impedance bandwidth (|S11| < −15 dB) of 43.2% (690‐1070 MHz) and harmonic suppression frequency up to 4.5 GHz are realized. In the operating frequency band (690‐960 MHz), port‐to‐port isolation of more than 35 dB, cross‐polarization discrimination of more than 27 dB, 3‐dB beamwidth of 68.8° ± 2.1°, efficiency of more than 82%, and stable gain of 8.2 ± 0.5 dBi are obtained by the proposed DPFA. In addition, radiation suppression of more than 18 dB in the interference bands (1690‐2690 MHz and 3300‐3800 MHz) is obtained.
