The meander-line technique, an acceptable approach for reducing the size of the radio frequency element, was proposed for reducing the size of coupler design. The proposed system is capable of covering wireless local areanetwork (WLAN) frequencies operating at 2.45 GHz and 5.8 GHz. Compared to the conventional size; the proposed couplers were reduced in size by 63 % and 56 % at 2.45 GHz and 5.8 GHz, respectively. The proposed, cascaded Butler matrices havethe ability to exhibit two types of beams, i.e., narrow and broad, by feeding the signal into the respective input port of the Butler matrix. The proposed design was etched from an inexpensive FR4 substrate. The methodology enabled the reduction of the area of the Butler matrix. A meander line with an area of 96 mm × 125 mm was used to replace the conventional, straight transmission line. This reduced the area of the Butler matrix by 36 % compared to the conventional matrix. The actual measurements showed very good agreement with the results obtained from simulations. 2014-04-21T02:14:23Z 2014-04-21T02:14:23Z 2013 Article Radioengineering, vol. 22(3), 2013, pages 769-775 1210-2512 http://www.radioeng.cz/papers/2013-3.htm http://dspace.unimap.edu.my:80/dspace/handle/123456789/33866 en Radioengineering Society |
