“…Several multilayer devices in SIW can also be found. A good revision of them is stated in [9], including filters [10], [11], couplers [12], power dividers [13]- [16], phase shifters [17] or antenna arrays [18]. The main advantage of all of them is their high degree of compactness.…”

Empty Substrate Integrated Waveguide has recently received special attention due to the fact that by removing the dielectric, this technology not only maintains the advantages of Substrate Integrated Waveguide circuits, but also improves their behaviour. Many circuits have been designed for Empty Substrate Integrated Waveguide, with several filters of different performance among them. The next challenge is to achieve the maximum possible compactness degree for these circuits. In this paper, we present the design of a multilayer Empty Substrate Integrated filter with the same performance as if it were manufactured in a single layer, but significantly increasing its compactness and mechanical resistance.

“…Hence, the design of compact sub-6G filters is a hot research topic for mobile portable devices. Substrate integrated waveguide (SIW) is widely used in RF passive device designs due to low loss, low cost, and flexibility of integration properties, such as filter [1][2][3][4][5][6], antenna [7][8][9][10][11], phase shifter [12][13][14][15][16], power divider [17][18][19][20][21], and coupler [22][23][24][25][26]. However, SIW filters under 6 GHz is still outsize to meet the requirement of portable communication devices because of the long wavelength.…”

A compact substrate integrated waveguide (SIW) filter based on composite right/lefthanded (CRLH) resonator units is implemented in this paper. The filter is composed of two CRLH resonator units serially connected by a SIW transmission line unit. The structure of the filter and equivalent circuit transmission behavior are analyzed, and a novel design method by optimizing the length and width of the interdigital metal slots to decrease the filter operation frequency is proposed. To further demonstrate the design theory and performance of the proposed filter, the filter was designed and fabricated on an RT6010 dielectric material. The measurement results show that the proposed filter works at a center frequency of 5.8 GHz with 200 MHz bandwidth The insertion loss is 2.3 dB, and the filter size is only 10 mm × 7.4 mm.

“…Similarly, [5] shows a reconfigurable phase shifter based on a piezoelectric actuator, where the side wall of the waveguide is in this case a perfect magnetic conductor (PMC). Other approaches to obtain phase shift employ PIN diodes [6,7,8,9,10,11,12]. Nevertheless, PIN diodes suffer from high losses in mm-wave regime.…”

In this paper, we present a low-loss mechanically reconfigurable phase shifter implemented in gap-waveguide technology for mm-wave frequencies. The proposed design gives a practical implementation of tuning elements inside the waveguide providing alternatives to the use of the E-plane split waveguide at high frequencies in order to avoid leakage losses. The depicted phase shifter design is based on a H-plane split waveguide. The phase shift is controlled by means of a tuning screw, which exerts pressure on a flexible metallic strip inserted inside the waveguide. The flexible strip bends with different curvature radii and determines the phase shift at the output port. Cost-effective manufacturing and simple implementation of the flexible metallic strip are achieved by means of the gap-waveguide design. A prototype has been manufactured for validation purposes. Good impedance matching is achieved from 64 GHz to 75 GHz providing a 15.8% impedance bandwidth. The results show a maximum phase shift of 250 o with a maximum and mean insertion loss of 3 dB and 1.7 dB, respectively.
