“…The compactness, easy fabrication, and multiple bands covering are three attractive features for the 5G millimeter wave (MMW) devices, such as filters, antennas, and power dividers. 2 Radio frequency (RF) filters are one of the most applicable components in communication systems that have some structures like stepped impedance resonators, parallel coupled lines, and multi-mode resonators. [2][3][4][5][6][7][8][9] Another dual-band filter with high rejection at stop-band and small bandwidth (BW) is introduced in Reference 6.…”

In this article, a dual-band sixth order double symmetric T-slot filter is proposed for the 5G communication systems. This filter contains two duplicate square resonators and a T-shape feedline on the Rogers RT duroid 5880 substrate. Operating at the 28 and 38.5 GHz frequencies from licensed 5G frequency bands and small size make this filter appropriate for different 5G applications. Furthermore, an LC equivalent circuit for the filter has been considered that helps us to have a better sight of this filter. Measurement results show good agreement with simulations. The attenuation on the passband is less than 1 dB. In order to evaluate the filter performance besides other millimeter waves components, a wideband antenna is combined with the filter to form a filtenna. The achieved results show the appropriate performance and well-matched with other 5G devices.

“…In general, several types of dual-mode micro-strip resonators have been available for filter applications, including rings, loops, circle patches or square patches. In addition, microstrip dual-mode filters can be in general divided into planar or multilayer structures according to implementation forms [3,4]. Due to these different types and structures of microstrip resonators, a variety of microstrip dual-mode filters have been designed.…”

A compact square patch band-pass filter is proposed in this paper. The dual-mode filter is designed based on a square patch resonator with a complementary split ring resonator (CSRR) split to be used as a perturbation element. The CSRR split is properly embedded in the square patch resonator to perturb electric current distribution on this patch and thus to simultaneously excite a pair of degenerate modes. Using the proposed CSRR elements, the band-pass filter is designed with miniaturized size, and two transmission zeros in stopbands are achieved to improve the selectivity of the filter. The influence of the CSRR elements on the band-pass filter is analyzed in detail. The proposed dual-mode filter is then fabricated and measured. Good agreement over a wide frequency range is achieved between the simulated and measured results. Moreover, in order to further investigate the characteristic of the dualmode patch filters with CSRR perturbation, a dual-mode filter with a rectangular ring slot is presented for comparative study.
