“…A compact dual-polarized antenna can achieve antenna filtering performance by integrating filtering Balun. 9,10 Magnetoelectric dipole with wide bandwidth, [11][12][13] stable gain, low profile, and so forth. The filtering effect can be achieved without increasing the size of antenna by introducing a filtering structure on the ground plane, 14 but it requires a relatively larger ground or a complex feed structure.…”

A compacted dual-polarized base station antenna with filtering characteristics and enhanced broadband is proposed for sub-6 GHz applications in this letter.The lower stopband radiation null is thus generated by the parasitic loops on the back of the substrate. In order to achieve the filtering response and extend the bandwidth of at the upper edge of the passband, a split strip-type dipole arm is added to the inner part of the annular dipole to form the radiation null.On the flip side, by changing the shape of the Balun ground, another filtering null is generated at the upper-band to suppress the second harmonic, achieving better broadband suppression performance. The experimental results show that the antenna has a 42.9% (3.3-5.1 GHz) impedance bandwidth, and the inband average gain reaches 8.3 dBi, while the out-of-band gain suppression is greater than 17 dB.

“…Generally, it is based on the filter synthesis approaches, where the antenna radiator acting as the last-stage resonator of the filter. [4][5][6][7] Although good filtering characteristic can be obtained, the ineluctable insertion loss is still introduced by the extra filtering circuit. To solve the problem, filtering antennas with less or without filtering circuits have been studied.…”

A broadband dual-polarized filtering antenna with a compact size and high skirt selectivity for fifth-generation (5G) sub-6 GHz applications is proposed in this paper. The antenna is composed of two feeding networks and four shorted patches, which is based on a slot-aperture excitation scheme. By employing the novel defected ground LC resonator structures (DGLCRSs) and two different types of open-ended structures, the proposed dual-polarized antenna realizes satisfactory filtering performance as well as an improved operating bandwidth simultaneously. During which, four radiation nulls are generated at the both band edges and can be individually controlled. To further enhance the upper stopband performance, four pairs of meander-shaped slots are inserted on the patches symmetrically, which introduces another controllable radiation null. The working mechanism for achieving the filtering responses is provided. A fabricated prototype and experimental results demonstrate that an impedance bandwidth of 42.9% (3.3-5.1 GHz) is first obtained in a low-profile dual-polarization structure, covering the entire 5G N77/N78/N79 bands. The measured gain is about 8.1 dBi within the passband, while the stopband suppression is better than 16 dB up to 1.85 f c . These merits make the proposed antenna quite potential for the 5G new radio communication systems.

This article presented a high selectivity and efficiency differential dual-polarized filtering patch antenna. A square driven patch together with a square parasitic patch are utilized to obtain a filtering performance. By loading an upper parasitic patch with a cross slot in the center, a radiation null is introduced on the high side of the passband. Two pairs of slots with the same size of folded U-shape are symmetrically etched on the diagonal of the driven patch, generating another radiation null on the low side of the passband. Thus, the antenna can achieve a good filtering gain response with two radiation nulls, realizing high selectivity. Additionally, as no extra filtering circuit is utilized, high radiation efficiency is also acquired. An antenna prototype is processed and measured, showing a bandwidth of 7.4%, high isolation of 32 dB, an antenna peak gain of 9 dBi and an efficiency of À0.29 dB in the center frequency.
