“…The SLR can be analyzed using the odd-and even-mode method, as previously detailed in [15]- [17]. When the odd-mode is excited, the center part of the SLR is equivalent to a shorted end and the resonant frequency can be approximately derived as,…”

“…Besides, the peak gains were only -1.8 dBi and 1.1 dBi at the two bands and many unwanted harmonics appeared between the two bands. In [15], the TM10 and TM30 modes of the patch were employed, but the gain was only -4 dBi and the feeding network was also complex. In [16], a tri-band filtering antenna was proposed by cascading a triband filtering with a wideband antenna.…”

“…To the best of the author's knowledge, the problems haven't been fully considered and solved. In [14] - [15], two dual-band filtering patch antennas were proposed. However, the rectangular patch in [14] works in two orthogonal polarizations at the two bands and very complicated matching structures were needed.…”

Abstract-A novel design of dual-band antenna with integrated filtering performance is proposed. A low-profile aperture-coupled U-slot patch antenna is employed for dual-band operation with a uniform polarization, which is fed by a dual-mode stub-loaded resonator (SLR). The U-slot patch works as a dual-mode resonator of the dual-band filter as well as the radiation element. The odd-and even-mode of the SLR are coupled and tuned with the U-slot patch, generating two 2 nd -order operation bands at 3.6 and 5.2 GHz. Compared with the traditional patch antenna, the proposed antenna exhibits improved bandwidth and frequency selectivity. In addition, the bandwidths can be controlled by adjusting the coupling strength between the SLR and the patch. Furthermore, the higher-order harmonics can be suppressed over a broadband without increasing the footprint of the design. Measured and simulated results agree well with each other, showing an excellent performance in terms of impedance matching, bandwidths, 2 nd -order filtering, out-of-band rejection, cross polarization discrimination (XPD) and gains at both bands.Index Terms-Dual-band, bandwidth, 2 nd -order, filtering, U-slot patch, harmonic suppression.

This paper presents a simple structure of dual-band filtering antenna for wireless application. The antenna is treated as radiating resonator. The filter of synthesis theory is applied to the design of the dual band filtering antenna. The theory can help us the guidance of processing design. The proposed dual band filtering antenna has simple structure and display excellent performance. The dual band filtering antenna presents characteristic of three order filter with high selectivity of pass-band and strong suppression of stop-band. The measured results show approximately agreement with the simulations.

“…System performance will be deteriorated due to introduced mutual couplings between bands when these frequency bands are close to each other. Hence, combination of antennas and filters into one device is extensively researched in recent years . Furthermore, large roll‐off level is required for filtering antenna design.…”

A dual-mode dual-band rectangular waveguide filtering antenna with fourth-order Chebyshev response is presented. First, design equations and processes of filtering networks are presented. Then, filtering antenna is constructed through cross-shaped slot for radiation instead of the output port of filtering networks. A pair of degenerated modes are exploited in waveguide resonator design to miniaturize the whole size and form two passbands. In addition, the bandwidth can be adjusted flexibly in proper range. A prototype at C-band is fabricated and measured, showing two operation channels of 5 to 5.05 GHz and 5.1 to 5.15 GHz with high rejection between two bands. Good agreement is achieved between the simulations and measurements, showing excellent performance in terms of filtering, out-of-band rejection, and gain in bands.
