The GGWG is implemented with glide symmetrical holes and the design frequency is 28 GHz. The low profile horns are integrated in the same waveguide wall as the slots. The designed antenna is a linear array of these horns but the solution can be easily extended to a planar array. Experimental results support this work. The designed antenna is a good candidate for applications related to 5G technologies where medium to high gains as well as high efficiencies are required and reasonable manufacturing costs are demanded.<\/jats:p>","DOI":"10.3390\/s20185311","type":"journal-article","created":{"date-parts":[[2020,9,17]],"date-time":"2020-09-17T10:08:59Z","timestamp":1600337339000},"page":"5311","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Array of Horns Fed by a Transverse Slotted Groove Gap Waveguide at 28 GHz"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2196-8112","authenticated-orcid":false,"given":"Malcolm","family":"Ng Mou Kehn","sequence":"first","affiliation":[{"name":"Department of Electrical Engineering, National Chiao Tung University, As Well As the \u201cCenter for mmWave Smart Radar Systems and Technologies\u201d at the Same University Under the Featured Areas Research Center Program within the Framework of the Higher Education Sprout Project by the Ministry of Education (MOE), Hsinchu 30010, Taiwan"}]},{"given":"Chih-Kai","family":"Hsieh","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering, National Chiao Tung University, As Well As the \u201cCenter for mmWave Smart Radar Systems and Technologies\u201d at the Same University Under the Featured Areas Research Center Program within the Framework of the Higher Education Sprout Project by the Ministry of Education (MOE), Hsinchu 30010, Taiwan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8012-9802","authenticated-orcid":false,"given":"Eva","family":"Rajo-Iglesias","sequence":"additional","affiliation":[{"name":"Department of Signal Theory and Communications, University Carlos III of Madrid, 28911 Legan\u00e9s, Spain"}]}],"member":"1968","published-online":{"date-parts":[[2020,9,17]]},"reference":[{"key":"ref_1","unstructured":"Johnson, R.C., and Jasik, H.
