5G Üst Bandı 38 GHz’de Çalışan Dikdörtgen Yamalı Mikroşerit Anten

Öz

Bu çalışmada alt yapısı PF-4 (kayıp tanjant 0,0001, yüksekliği 2 mm) ‘ten, iletken malzeme olarak bir tarafı yapışkan bakır banttan oluşan yamasının boyutları 6,5mmx2,5mmx2mm olan dikdörtgen mikroşerit anten tasarlanmıştır. Antenin boyutlarının küçük olmasına karşın, benzetim sonuçlarından antenin kazancı 9,512 dB, yöneltimi 10,47 dBi, yansıma katsayısı 0,16, gerilim duran dalga oranı 1,239, 3dB açıklığı 28,7⁰, verimi % 90,80, bant genişliği (35,642GHz-41,627 GHz) 5,985GHz ve çalışma frekansı 38 GHz’dir. Antenin karakteristik değerlerine (yansıma katsayısı 0,106 idealde bu değer sıfır, Gerilim Duran Dalga Oranı (GDDO) 1,239 idealde bu değer 1’dir) bakıldığında antenin ne kadar iyi tasarlandığı görülmektedir. Ayrıca 3 dB açıklığının 28,7⁰ gibi dar bir açı olması yönlülüğün ne kadar iyi olduğunu göstermektedir. Antenin bundan sonra 5G üst bandında çalışacak araştırmacılara ışık tutacağını düşünüyorum.

Rectangular Patch Microstrip Antenna Operating at 5G Upper Band 38 GHz

Abstract

In this study, a rectangular microstrip antenna with the dimensions of 6,5mmx2,5mmx2mm, of the substructure of PF-4 (lost tangent 0,0001, height 2 mm) and a patch consisting of an adhesive copper tape as conductive material, was designed. Although the dimensions of the antenna are small, the simulation results show that the gain of the antenna is 9,512 dB, the directivity is 10,47 dBi, the reflection coefficient is 0,16, the voltage standing wave ratio is 1,239, the 3dB aperture is 28,7⁰, the efficiency is 90,80%, the bandwidth is (35,642GHz-41,627 GHz) 5,985GHz GHz and the operating frequency is 38 GHz. When the characteristic values of the antenna (reflection coefficient is 0,106 ideally this value is zero, Voltage Standing Wave Ratio (VSWR) is 1,239 ideally this value is 1), it is seen how well the antenna is designed. Also, the narrow angle of the 3 dB opening is 28,7⁰, showing how good the directionality is. I think the antenna will shed light on researchers who will work in the 5G upper band from now on.
