Abstract

This study presents an E-shaped array microstrip antenna design with a reflector, which has a high gain for short-range radar studies. E-shaped dipoles at the top of the substrate are brought into contact with an irregular microstrip line, which is the bottom of FR-4 substrate. The antenna feed is excited using a coaxial cable. The substrate material and the chrome reflector are attached to each other with Teflon material. The proposed antenna provides 7.85 and 9.62 dBi gains at resonance frequencies of 1.4 and 2.4 GHz, respectively. This antenna also has an F/B ratio of over 15 dB and an HPBW (half power beam width) value able to be used for short-ranges.

RADAR UYGULAMALARİ İÇİN 1.4 ve 2.4 GHz REFLEKTÖRLÜ MİKROŞERİT DİZİ ANTENİ

Abstract

Bu çalışmada kısa menzilli radar çalışmaları için kazancı yüksek olan, reflektörlü E şeklinde dizili mikroşerit anten tasarımı sunulmaktadır. Substratın tepesindeki E şeklindeki dipoller, FR-4 substratının tabanı olan düzensiz bir mikroşerit hattı ile temas ettirilir. Anten beslemesi koaksiyel bir kablo kullanılarak uyarılır. Alt tabaka malzemesi ve krom yansitici birbirine Teflon malzeme ile tutturulmuştur. Önerilen anten, 1,4 ve 2,4 GHz rezonans frekanslarında sırasıyla 7.85 ve 9.62 dBi kazanç sağlamaktadır. Bu anten ayrıca 15 dB'in üzerinde F/B oranına ve kısa mesafeler için kullanılabilecek bir HPBW (half power beam width) değerine sahiptir.
