In this research paper, an automated design technique is used to optimize the variables of a microstrip patch antenna (MSPA), for reliable broadband communication systems. The method is based on a computerized procedure to produce a special defect in the ground plane, alongside with dimensions optimizing using genetic algorithm. Conventionally, either cut and try, or dimension optimization is used separately for this purpose. The novelty of the method presented here resides in the fact that the

The resulting antenna gave a return loss of less than-10dB between 3GHz and 8GHz i.e. a bandwidth of 5GHz. Compared to other literature techniques, the achieved bandwidth is considered to be the best. The dimensions and the bandwidth of the designed antenna are attractive for next generation communication systems. ‫ﻣﺤﺴﻦ‬ ‫آﻟﻲ‬ ‫ﺗﺼﻤﯿﻢ‬ ‫أﺳﻠﻮب‬ ‫ﺧﺎص‬ ‫اﻟﻤﺎﯾﻜﺮوﺳﺘﺮب‬ ‫ﻟﮭﻮاﺋﻲ‬ ‫ذات‬ ‫اﻟﻤﺎﯾﻜﺮووﯾﻒ‬ ‫ﻻﺗﺼﺎﻻت‬ ‫اﻟﻌﺮﯾﺾ‬ ‫اﻟﻨﻄﺎق‬ ‫اﻟﺨﻼﺻﺔ‬ ‫اﻟﻤﺎﯾﻜﺮوﺳﺘﺮب‬ ‫ھﻮاﺋﻲ‬ ‫ﻣﺘﻐﯿﺮات‬ ‫ﻟﺘﺤﺴﯿﻦ‬ ‫آﻟﻲ‬ ‫ﺗﺼﻤﯿﻢ‬ ‫أﺳﻠﻮب‬ ‫اﺳﺘﺨﺪام‬ ‫ﺗﻢ‬ ،‫اﻟﺒﺤﺚ‬ ‫ھﺬا‬ ‫ﻓﻲ‬) MSPA (‫ﻟﻨﻈﻢ‬ ‫ﺧﺎص‬ ، ‫اﻟﻤﺎﯾﻜﺮووﯾﻒ‬ ‫ﺣﺰﻣﺔ‬ ‫ﻓﻲ‬ ‫اﻟﻌﺮﯾﺾ‬ ‫اﻟﻨﻄﺎق‬ ‫ذات‬ ‫اﻻﺗﺼﺎﻻت‬. ‫إﺟﺮاء‬ ‫إﻟﻰ‬ ‫ﯾﺴﺘﻨﺪ‬ ‫اﻷﺳﻠﻮب‬ ‫ات‬ ‫ﺧﺎص‬ ‫ﻗﻄﻊ‬ ‫ﻹﻧﺘﺎج‬ ‫ﻣﺤﻮﺳﺒﺔ‬ ‫ا‬ ‫اﻟﻠﻮﺣﺔ‬ ‫ﻓﻲ‬ ‫اﻟﺠﯿﻨﯿﺔ‬ ‫اﻟﺨﻮارزﻣﯿﺔ‬ ‫ﺑﺎﺳﺘﺨﺪام‬ ‫اﻟﻤﺜﻠﻰ‬ ‫اﻷﺑﻌﺎد‬ ‫اﯾﺠﺎد‬ ‫ﻣﻊ‬ ‫ﺟﻨﺐ‬ ‫إﻟﻰ‬ ‫ﺟﻨﺒﺎ‬ ،‫ﻟﻠﮭﻮاﺋﻲ‬ ‫ﻻرﺿﯿﺔ‬. ‫اﺳﺘﺨﺪام‬ ‫ﯾﺘﻢ‬ ،‫ﺗﻘﻠﯿﺪﯾﺎ‬ ‫ا‬ ‫اﻻﺑﻌﺎد‬ ‫أو‬ ،‫واﻟﻤﺤﺎوﻟﺔ‬ ‫اﻟﻘﺺ‬ ‫ﻟﻤﺜﻠﻰ‬ ‫اﻟﻐﺮض‬ ‫ﻟﮭﺬا‬ ‫ﻣﻨﻔﺼﻞ‬ ‫ﺑﺸﻜﻞ‬. ‫أن‬ ‫ﻓﻲ‬ ‫ﺗﻜﻤﻦ‬ ‫اﻟﺒﺤﺚ‬ ‫ھﺬا‬ ‫ﻓﻲ‬ ‫اﻟﻤﻌﺮوﺿﺔ‬ ‫اﻟﻄﺮﯾﻘﺔ‬ ‫ﺣﺪاﺛﺔ‬ ‫ﻣﻌﺎ‬ ‫اﺳﺘﺨﺪﻣﺖ‬ ‫اﻵﻟﻲ‬ ‫اﻟﺘﺤﺴﯿﻦ‬ ‫وﺗﻘﻨﯿﺔ‬ ،‫اﻟﻘﺺ‬ ‫ﺗﻘﻨﯿﺔ‬ ‫ﺑﺸﻜ‬ ‫ﻣﺤﻮﺳﺐ‬ ‫ﻞ‬ ‫ھﻮاﺋﻲ‬ ‫ﻹﻧﺘﺎج‬ ‫ﻋﺮﯾﻀﺔ‬ ‫ﺣﺰﻣﺔ‬ ‫ذو‬. ‫اﻟﮭﻮاﺋﻲ‬ ‫أﻋﻄﻰ‬ ‫ﻗﺪرھﺎ‬ ‫ﻋﺮﯾﻀﺔ‬ ‫ﺣﺰﻣﺔ‬ ‫ذﻟﻚ‬ ‫ﻋﻦ‬ ‫اﻟﻨﺎﺟﻢ‬ 5 ‫ﺑﯿﻦ‬ ‫ھﯿﺮﺗﺰ‬ ‫ﻛﯿﻜﺎ‬ 3 ‫و‬ 8 ‫ﻛﯿﻜﺎھﺮﺗﺰ‬. ‫ﯾﻌﺘﺒﺮ‬ ،‫اﻟﺤﺪﯾﺜﺔ‬ ‫اﻟﺘﻘﻨﯿﺎت‬ ‫ﻣﻦ‬ ‫ﺑﻐﯿﺮھﺎ‬ ‫ﻣﻘﺎرﻧﺔ‬ ‫اﻵن‬ ‫ﺣﺘﻰ‬ ‫اﻷﻓﻀﻞ‬ ‫ھﻮ‬ ‫اﻟﻤﺤﻘﻖ‬ ‫اﻟﺤﺰﻣﺔ‬ ‫ﻋﺮض‬. ‫ﻣﻔﯿﺪة‬ ‫اﻟﺒﺤﺚ‬ ‫ھﺬا‬ ‫ﻓﻲ‬ ‫اﻟﻤﺼﻤﻢ‬ ‫ﻟﻠﮭﻮاﺋﻲ‬ ‫اﻟﺘﺮددي‬ ‫اﻟﻨﻄﺎق‬ ‫وﻋﺮض‬ ‫اﻷﺑﻌﺎد‬ ‫ﻟ‬ ‫اﻟﻘﺎدم‬ ‫اﻟﺠﯿﻞ‬ ‫اﺗﺼﺎﻻت‬ ‫ﻨﻈﻢ‬ .
