The effect on the direction of the main beam of those arrays (linear and planar) will be studied. We are going to compare our theory used and programmed in MATLAB by one simulations executed in the PCAAD (Personal Computer Aided Antennas Design) software [2].However, we are going to explore the radiation pattern by the variation of the excitation phase of patches of a square array for four rectangular microstrip patches antennas array, as we takes the same elements of the previous linear array[3], [4], and we are going to put them under shape of a planar square array.<\/jats:p>","DOI":"10.1145\/1132512.1127024","type":"journal-article","created":{"date-parts":[[2009,10,6]],"date-time":"2009-10-06T18:18:59Z","timestamp":1254853139000},"page":"1-13","update-policy":"http:\/\/dx.doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["A comparison the performances of linear and planar array of the four patchs antennas by the software matlab"],"prefix":"10.1145","volume":"2006","author":[{"given":"A.","family":"Latif","sequence":"first","affiliation":[{"name":"Faculty of Sciences Semlalia, Laboratory of Electronics and Instrumentation, Marrakech, Morocco"}]},{"given":"A.","family":"Oulad-Said","sequence":"additional","affiliation":[{"name":"Royal School of Air, Microwaves and Telecommunications Laboratory, Marrakech, Morocco"}]},{"given":"A.
