“…from 18% to 23%. This is very close to the filters from[2,4,6,9,10,16,17,18,19] mentioned in TABLE II, which we will call "comparable" filters. Other filters in the literature have significantly lower relative bandwidths, of the order of 10%[3], but with very high insertion loss (9.3 dB).…”

“…The filter in [2] also presents a 𝑄 𝑢 equal to 26, but its size is relatively large. Finally, compared to the filters presented in [19], made within our group and operating around 120 GHz, the performance of the patch filters is slightly better, with slightly larger dimensions for the patch filters at 120 GHz. Also it is worth to mention that measured filters for with asymmetric response has sharp left selectivity of 0.76.…”

“…Also it is worth to mention that measured filters for with asymmetric response has sharp left selectivity of 0.76. It should be noted, however, that the filters presented in [19] call for a more complex design based on the use of coupled lines, with the need to properly control parasitic couplings. This last aspect, namely the simplicity of design, argues in favor of patch filters, which are based on simple structures (apart from the problem of taking dummies into account, depending on each technology), and whose design could be described through simple steps usable by mm-wave circuit designers.…”

“…More generally, the literature has encountered few works for passive filters that operate at mm-wave band and implemented on CMOS/BiCMOS technologies [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. And, only a single work exists for bandpass filter operating beyond 100 GHz [19]. It uses the coupled S-CPW topology to have flexible responses with reduction of losses and existence of transmission zeros (TZs).…”

In this paper, the patch concept is applied to the design of millimeter-wave band-pass filters in BiCMOS 55 nm technology. The operation frequencies are 120 GHz and 200 GHz, respectively. A via- and slot-based approach makes filters very compact, albeit patch-based, through a multi-mode approach. At 200 GHz, the side of the patch is only 194 μm long, or about a quarter wavelength, compared to half a wavelength for a conventional patch. The dependence of performance on the thickness of the Back-End-Of-Line is studied, and the design method is detailed. The performance is very good, with for example a filter operating at 200 GHz with a relative bandwidth of 23% and insertion loss of 3 dB. Finally, the prospect of using a thicker Back-End-Of-Line, offered as an option in 55-nm BiCMOS technology, makes it possible to show that even better performance can be achieved, with insertion loss below 3 dB.

In this work, fabrication of frequency selective surface filters by coating paper with silver ink and subsequent laser etching the frequency filter pattern has been investigated. Three filter structures consisting of a combination of square and ring patches operating at 102, 113, and 126 GHz and with corresponding signal attenuation of −15.2, −15.4, and −14.5 dB were fabricated and simulated; −5 dB bandwidths were following, , respectively. Also, the proposed screen printing with assistive laser etching could be used to reduce the number of used screens. Furthermore, paper based fabrication using a biodegradable ink could be an alternative fabrication process in future electronic manufacturing.
