“…, dual‐mode stub‐loaded resonators are introduced into the coupling feedlines, and a dual‐band bandpass filtering response for the patch antenna is generated. Recently, some other methods tend to use less filters or concentrate on the filtering response of radiators . For example, in Refs and filtering responses of the antennas are obtained by introducing open stubs in feedlines.…”

A differentially fed, dual‐band microstrip patch antenna with filtering response is proposed in this letter. By etching an H‐shaped slot at a rectangle radiating patch, two resonant modes of the patch antenna, as well as an additional radiation null between the two operation bands are generated. Besides, two symmetric open‐stub coupling feedlines (OSCFs) are introduced to differentially excite the antenna, which offer two extra radiation nulls outside the two bands. Thus, a dual‐band bandpass filtering response for the proposed antenna is obtained. Measurement results of the prototype show good agreement with the simulated ones. Stable radiation patterns with low cross‐polarization levels of better than 28 dB are observed. Besides, a deep roll‐off of better than 22 dBi for the realized gain is also obtained.

“…As a consequence, a variety of filtennas have been developed. Examples include filtering horn antennas [1]- [3], substrate integrated waveguide (SIW) filtennas [4], [5], planar filtering ultra-wideband (UWB) antennas [6], [7], filtering microstrip patch antennas [8]- [11], filtering slot antennas [12], and filtering quasi-Yagi antennas [13].…”

“…The function of the antenna is receiving and transmitting signal, and the bandpass filter is used to filter spurious signals. In general, these two components are designed separately [1][2][3], but many scholars start to study the co-design method and other methods to realize filtering antennas [4][5][6][7][8][9][10][11][12][13][14][15]. Filtering antennas not only improve the performance of communications systems, but also minimize the total size.…”

Abstract-A filtering antenna based on a dumbbell-shaped resonator is proposed, fabricated and measured. A Γ-shaped antenna and the proposed dumbbell-shaped resonator are used and integrated to be a filtering antenna. The Γ-shaped antenna which acts as a radiator is excited by a coupled line. Measured results show that the filtering antenna achieves an impedance bandwidth of 6.7% at a reflection coefficient |S 11 | < −10 dB and has a gain of 1.35 dBi. Moreover, a radiation zero occurs at 3.1 GHz. Compared with the characteristics of fundamental Γ-shaped antenna, the design of the dumbbell resonator has little impact on antenna's radiation patterns. In addition, to explain the mechanism of filtering antenna, the analysis of surface current distribution on patch is given. The size of filtering antenna is 0.33λ 0 × 0.17λ 0 (λ 0 is the free-space wavelength at 2.45 GHz). Compared to other recent works, a simpler structure and more compact size are the key features. Owing to the operating bandwidth and the characteristic of filtering, the proposed antenna can be used in modern wireless communications systems.
