“…As seen, the proposed filter has the best frequency selectivity with the narrowest bandwidth, while achieving the smallest footprint area. Particularly, the new design has a 31.6% size reduction and 15.2% bandwidth reduction compared to the SIEW septa filter [13]. The measured insertion loss is higher than most other filters in Table 1 except for the one in [6].…”

“…In SIEW, two copper strips are inserted at the middle height and intersect all the through holes that emulate the vertical wall. The additional copper strips allow the longitudinal current flow [12,13]. Since its invention, SIEW has been used to design an E-plane horn antenna and an array [14,15], a dual linearly polarized horn antenna [13], and an SIEW adaptor that excites circular polarization [16].…”

“…The invention of SIEW antenna calls for the needs for SIEW filters because SIW filters are difficult to integrate with SIEW antennas. The first SIEW filter published in [13] was based on metallic septa. This type of design is normally longer than other filter types because the additional septa widths increase the filter length.…”

Substrate integrated E-plane waveguide (SIEW) was invented recently to design E-plane waveguide devices on printed circuit board, which cannot be achieved by using the conventional substrate integrated waveguide (SIW). This paper is the first time to present an E-plane displaced SIEW junctions bandpass filter. The proposed design is shorter than the recently published SIEW septa filter and has a smaller footprint than several other SIW filters. It is designed by mapping an equivalent E-plane waveguide filter to its SIEW implementation. A filter prototype is built and measured for validation.

“…In order realize broadband and dual polarized SIW horn antenna, the multilayers SIW structure is adopted. [9][10][11][12] An E-plane horn antenna is realized by using the double-layers SIW structure, 9 which achieves wider impedance bandwidth, higher gain and radiation efficiency, but only one polarization state. In references 10,11, the double-layers SIW structure is also used to achieve the E-plane horn antenna with dual linearly polarized function, but the impedance bandwidth still needs to be further improved.…”

“…Generally, horn antennas designed based on a two‐dimensional single‐layer SIW structure can only achieve single polarization, and it is difficult to obtain multipolarization function. In order realize broadband and dual polarized SIW horn antenna, the multilayers SIW structure is adopted 9–12 …”

A circularly polarized pyramidal horn antenna based on substrate integrated waveguide (SIW) technology is proposed and developed for Ku-band applications. The proposed horn antenna is excited by the upper and lower SICL differential feed networks placed vertically to each other, so that two orthogonal waveguide modes with the equal amplitude are generated at the horn aperture. A 90 coupling network based on SICL technology is proposed to achieve a 90 phase difference between the two orthogonal waveguide modes, thus realizing the function of left-hand circular polarization (LHCP) and right-hand circular polarization (RHCP) of the horn antenna. In addition, in order to make the phase distribution of the horn aperture more uniform, a cross metal strip structure at the horn aperture is proposed, thereby improving the radiation efficiency.The proposed horn antenna is manufactured by using low-cost printed circuit boards (PCBs) process. The measured results show that the proposed circularly polarized pyramidal horn operates at center frequency 12.5 GHz, the measured gain is 8.4 dBi, the relative standing wave and axial ratio (AR) bandwidth are approximately 24% and 5%, respectively. And the radiation aperture efficiency is as high as 78.5%. The developed circularly polarized pyramidal horn antenna can be applied in the field of satellite communications.
