Mikroşerit antenler (MA), diğer mikrodalga antenlere olan bazı üstünlükleri nedeniyle günümüzde kablosuz haberleşmenin hemen hemen her alanında kullanılmaktadırlar. MA’ların iletken kısımlarında modifikasyon yaparak kompakt mikroşerit antenler (KMA) elde edilir. KMA’nın MA’ya göre temel avantajı, aynı rezonans frekansı için önemli oranda daha küçük boyutlarda gerçekleştirilmesidir. Literatürde, dikdörtgen halka şekilli KMA (DHKMA), C şekilli KMA (CKMA), E şekilli KMA (EKMA),  H şekilli KMA (HKMA) ve L şekilli KMA’ların (LKMA) rezonans frekansı hesabı için yapay sinir ağları (YSA) ve/veya bulanık mantık sitemine dayalı uyarlanır ağ (BMSDUA) modelleri kullanılmıştır. Slot yüklü bu KMA’ların rezonans ferkansı hesabı için kullanılan YSA ve BMSDUA modelleri ile elde edilen sonuçlar, literatürdeki diğer metotlar ile elde edilen sonuçlar ile karşılaştırılmış ve daha başarılı olduğu görülmüştür. Bu sonuçlara göre düzgün geometriye sahip olmayan slot yüklü KMA’ların rezonans frekansı hesabı için yapay zeka tekniklerinden YSA ve BMSDUA ağlarının başarılı bir şekilde kullanılabileceği görülmektedir. Ayrıca YSA ve BMSDUA çalışmaları incelendiğinde diğer metotlara göre daha hızlı ve etkili olduğu sonucu ortaya çıkmaktadır. Bu tarama çalışmasında, slot yüklü KMA’ların rezonans frekansı hesabı için literatürde sunulan YSA ve BMSDUA modellerini kullanan çalışmalar incelenmiş ve sonuçlar diğer metotlarla elde edilen sonuçlar ile karşılaştırılmıştır.
