The tunability is achieved by breaking and regenerating the glide symmetry. The filters are made of two glide-symmetric pieces that can be displaced in a certain direction, and therefore, break the symmetry. The high filtering capacity of these designs is demonstrated by simulation and measurement and can also be adjusted mechanically. The transmission level in the manufactured filter varies from a value between \u22121 and \u22122 dB when the filter is in the glide symmetry position to values close to \u221240 dB in the stop-band when it is in the broken symmetry position. The transmission band obtained in the symmetrical mode is around 20%, but, after breaking the symmetry, it is split into two passbands of 6.5% and 11% separated by a stop-band of 6%. The position, bandwidth, filtering level and filter roll-off can be adjusted for both modes of operation by appropriately selecting the unit cell design parameters and the number of unit cells.<\/jats:p>","DOI":"10.3390\/s22031001","type":"journal-article","created":{"date-parts":[[2022,1,27]],"date-time":"2022-01-27T22:01:57Z","timestamp":1643320917000},"page":"1001","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Mechanically Reconfigurable Waveguide Filter Based on Glide Symmetry at Millimetre-Wave Bands"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2322-3800","authenticated-orcid":false,"given":"Adrian","family":"Tamayo-Dominguez","sequence":"first","affiliation":[{"name":"Information Processing and Telecommunications Center, Universidad Polit\u00e9cnica de Madrid, 28040 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9296-4098","authenticated-orcid":false,"given":"Jos\u00e9-Manuel","family":"Fern\u00e1ndez-Gonz\u00e1lez","sequence":"additional","affiliation":[{"name":"Information Processing and Telecommunications Center, Universidad Polit\u00e9cnica de Madrid, 28040 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4900-4788","authenticated-orcid":false,"given":"Oscar","family":"Quevedo-Teruel","sequence":"additional","affiliation":[{"name":"Division of Electromagnetic Engineering, KTH Royal Institute of Technology, 10044 Stockholm, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"63752","DOI":"10.1109\/ACCESS.2021.3075060","article-title":"Evaluation of a Planar Reconfigurable Phased Array Antenna Driven by a Multi-Channel Beamforming Module at Ka Band","volume":"9","year":"2021","journal-title":"IEEE Access"},{"key":"ref_2","first-page":"84","article-title":"A Reconfigurable Microwave Combline Filter","volume":"63","author":"Yuceer","year":"2016","journal-title":"IEEE Trans.
