“…In [8], novel multiplexers were demonstrated based on all-resonator structures, eliminating the conventional transmission-line based signal distribution networks. The integration of filters and antennas has attracted significant research interests during the past several years [9]- [22]. By virtue of their resonant nature, some antennas can serve as the last resonators of the filters.…”

“…As a result, the antennas can contribute to the poles of the filter and therefore the bandwidth and frequency selectivity. In [9], a microstrip filtering antenna array was proposed by using coupled resonators to design the feeding network. To the best of our knowledge, [9] was the only filtering array previously demonstrated in the literature.…”

“…In [9], a microstrip filtering antenna array was proposed by using coupled resonators to design the feeding network. To the best of our knowledge, [9] was the only filtering array previously demonstrated in the literature. Compared with [9], the filtering array in this paper achieves a much wider bandwidth (5.6% versus 3.0%) and a higher order filtering (4 th order versus 3 rd order) with a similar shape factor of a 2 × 2 array.…”

The device employs a multi-port network of coupled resonators, which is synthesized and designed as a whole to fulfill the functions of filtering, power combination/division and radiation. The 50 Ω interfaces between the cascaded filter, power divider and antenna in traditional RF front-ends are eliminated to achieve a highly integrated and compact structure. A novel resonator-based four-way out-of-phase filtering power divider is proposed and designed. It is coupled to the patch array, rendering a fourth-order filtering response. The coupling matrix of the resonator network is synthesized. The physical implementations of the resonators and their couplings are detailed. Compared to a traditional patch array, the integrated filtering array shows an improved bandwidth and frequency selectivity. In addition, the harmonic of the antenna array is suppressed due to the use of different types of resonators. To verify the concept, a 2 × 2 filtering array at S band is designed, prototyped and tested. Good agreement between simulations and measurements has been achieved, demonstrating the integrated filtering antenna array has the merits of wide bandwidth, high frequency selectivity, harmonics suppression, stable antenna gain and high polarization purity.

“…Many filtering antennas, in different topologies, have been designed using filter synthesis approach, in which the antenna acts as the last resonator in the filter. Filtering antennas have been implemented in different forms including rectangular patch [1], circular patch [2], patch array [3], Γ-shaped antenna [4], slot dipole [5], monopole antenna [6], inverted-L antenna [7], Yagi antenna [8], waveguide slot antenna [9], and dielectric resonator antennas [10].…”

Abstract-Design, simulation, and measurement of a compact filtering microstrip antenna is presented. A feed line, two hairpin resonators, and a rectangular patch are integrated to form the filtering antenna. The elements together function as a third order bandpass filter with Chebyshev equal ripple response of 0.043 dB at midband frequency of 2.0 GHz. The rectangular patch acts not only as a radiating element, but also as the last resonator of the bandpass filter. The proposed filtering antenna exhibits good out-ofband gain suppression, flat in-band gain response, good selectivity at the band edges, and well-shaped radiation pattern.

“…Hence, a dual-band array structure is preferred due to its simple system configuration and cost minimisation. Although similar work is proposed in [2] and [3], but is disadvantageous with respect to a few qualities; such as, 3 rd order filters being used, larger 2x2 array structures, single-band operation and final response not being sufficiently sharp. In this presented work, a dualband 1x2 antenna array with 2 nd order integrated filters is designed, modelled and simulated.…”

Abstract:This paper presents the design, modelling and results of a dual-band antenna array integrated with filters. The array is fed via a single 50 Ω port and consists of two radiating elements. Hence, a 1x2 array structure. The two bands of the antenna array correspond to the two WLAN bands of 2.4 GHz and 5.8 GHz. Other than the two fundamental resonant frequencies, the standalone array has spurious harmonics at various other frequencies. For the suppression of these harmonics, the array is integrated with two bandpass filters, centered at 2.4 GHz and 5.8 GHz. The antenna array with integrated filters was electromagnetically modelled and the simulation results have been presented. The acquired results are considerably acceptable; showing the array to have dual-bands at 2.4 GHz and 5.8 GHz, at a return loss of more than 20 dB, and also successful suppression of the spurious harmonics of the antenna array.
