“…In order to improve the EMC performance of multi-functional SSPP channels, the SIP technology is proposed with compact size and easy fabrication. The substrate integrated (SI) technology has attracted extensive attention of researchers due to its excellent electromagnetic performance and easy integration with modern planar circuit technology [45][46][47][48]. When electromagnetic waves propagate in the SI waveguide, their electric field distributions are similar with the rectangular waveguide.…”

High integration of modern microwave circuits and systems puts forward higher requirements for multi-function and electromagnetic compatibility (EMC) performance of transmission channels. In this paper, we design a multi-functional spoof surface plasmon polariton (SSPP) channel which can realize continuous phase modulations more than 180° in X-band and continuous amplitude modulations from -1dB to -40dB in Ku-band. Based on the multi-functional SSPP channel, we propose two EMC technologies, including the substrate integrated packaging (SIP) method and the tunable wavenumber mismatching (TWM) method. The SIP method can effectively isolate the inside and outside of the package to avoid mutual interference with easy fabrication and compact size (0.13 λ0 × 0.043 λ0). Meanwhile, simulated and measured results demonstrate that the coupling coefficient of the packaged SSPP channels is about 8-10dB lower than that without packaging, and 13-15dB lower than that of traditional microstrip channels in the whole X-band and Ku-band. The TWM method is realized by designing the wavenumber difference between two channels. Simulated and measured results demonstrate that the coupling coefficient of two adjacent channels with a distance of 1/30 λ0 can be reduced to around -30dB in varied frequency bands. Therefore, the two proposed EMC technologies have application potentials of highly integrated microwave circuits and systems to achieve multiple functions and good EMC performance.

“…SIWs are integrated waveguide-like structures fabricated by using two rows of conducting cylinders or slots embedded in a dielectric substrate. The SIW functions as a traditional waveguide on the substrate [16]. Owing to the similarity between the SIW and rectangular waveguide, an empirical relationship between the geometric size of SIW with the same propagation ability and the effective width of the rectangular waveguide can be established as follows [17]:…”

A completely asymmetrical dual-band micro-strip filter combined with a complementary split ring resonator (CSRR) consisting of a circle and a square, and substrate integrated waveguide (SIW) is presented in this paper. The proposed design can be applied in the Industrial Scientific Medical (ISM) band. The CSRR of this completely asymmetrical filter, which has both square and circular parts, can realize two distinct passbands and shows higher out-of-band rejection than symmetrical filters; it is an asymmetrical complementary split ring resonator (ACSRR). The out-ofband rejection level between two passbands can reach 40 dB, compared to 35 dB in a circular filter and 30 dB in a square filter. The measured results are in good agreement with simulated results. key words: asymmetrical complementary split ring resonator (ACSRR); substrate integrated waveguide (SIW); dual-band filter; high out-of-band rejection Classification: Microwave and millimeter wave devices, circuits, and hardware

Low-cost printed circuit board waveguide (PCBWG) technology is employed to develop new waveguide-fed microstrip antenna arrays with low profile and light weight while maintaining high efficiency and gain at 12.5 GHz. The proposed corporate feed network has two parts: on the antenna layer, microstrip lines are used to form a 2 3 4 sequentially rotated sub-array of circularly polarized microstrip patches and on the feed layer PCB-WG is utilized to combine any number of these sub-arrays to form a larger array. Because PCB-WGs transmit the power over a large portion of the feed network, losses are substantially reduced and spurious radiations from feed circuit are eliminated. Several microstrip arrays with PCBWG feed were designed and fabricated using standard PCB process. Comparing the results with those of a hybrid array with conventional waveguide feed shows that there is only a negligible degradation in gain and efficiency when bulky and expensive aluminum waveguides are replaced by PCB-WGs.
