Abstract
Bu bildiride, orta menzil otomotiv radarlarında kullanılmak üzere ±45° eğik polarizasyona, -20 dB yan kulakçık seviyesine sahip ve kazancı 16.3 dB, yarı güç hüzme genişliği yanca ekseninde 10° olan bir mikroşerit dizi anten sunulmuştur. Genlik bastırma yöntemleri ile tasarlanan seri besleme devresi dizi antenin beslemesinde kullanılmış ve düşük yan kulakçık seviyesi elde edilmiştir. Böylece yanlış alarm oranı azaltılmıştır. Yama anten dizisinin polarizasyonu ±45° eğik olacak şekilde ikinci bir besleme hattı yerleştirilmiş ve böylece çift polarizasyon özelliği elde edilerek toplanan bilginin doğruluğu arttırılmıştır. Bilgisayar destekli tasarım programı ile benzetimi yapılan antenin sonuçları ile orta menzil otomotiv radarlarının ihtiyaç duyduğu anten özellikleri karşılanmıştır.

Abstract
In this paper, a microstrip array antenna with ±45° slant polarization, -20 dB side lobe level and 16.3 dBi gain, half power beamwidth 10° in the azimuth axis is presented for use in mid-range automotive radars. In the array antenna, low side lobe level is obtained by using the serial feeder circuit designed with amplitude suppression methods. Thus, the false alarm rate is reduced. A second feed line was placed with the polarization of the patch antenna array tilted by ±45°, thus increasing the accuracy of the collected information by obtaining the double polarization feature. With the results of the antenna simulated with the computer aided design program, the antenna features required by the mid-range automotive radars have been met.
