The concept presented here can be implemented in any structure that has a microstrip in its configuration. The EBG structure is first analyzed using a full wave electromagnetic solver and then optimized to work at WLAN band (5.15\u20135.825 GHz). Two UWB passband filters are used to demonstrate the applicability and effectiveness of the novel EBG notch band feature. Simulation results are provided for two cases studied.<\/jats:p>","DOI":"10.3390\/s101109620","type":"journal-article","created":{"date-parts":[[2010,11,2]],"date-time":"2010-11-02T10:22:51Z","timestamp":1288693371000},"page":"9620-9629","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Compact Electromagnetic Bandgap Structures for Notch Band in Ultra-Wideband Applications"],"prefix":"10.3390","volume":"10","author":[{"given":"Mihai","family":"Rotaru","sequence":"first","affiliation":[{"name":"School of Electronics and Computer Science, University of Southampton, Southampton, SO17 1BJ, UK"}]},{"given":"Jan","family":"Sykulski","sequence":"additional","affiliation":[{"name":"School of Electronics and Computer Science, University of Southampton, Southampton, SO17 1BJ, UK"}]}],"member":"1968","published-online":{"date-parts":[[2010,11,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2059","DOI":"10.1109\/22.798001","article-title":"High-impedance electromagnetic surfaces with a forbidden frequency band","volume":"47","author":"Sievenpiper","year":"1999","journal-title":"IEEE Trans.
