Abstract

In this study, a new electrically frequency tunable planar inverted-F antenna (PIFA) design is proposed for WLAN and WiMAX applications. The main radiator of the antenna with dimensions of 30 × 25 × 10 mm3
consists of unsymmetrical meander line elements and the frequency response can be adjusted dynamically by means of a PIN diode used in the optimum position between these elements. The prototype fabrication of the antenna, whose numerical design was carried out using Ansoft-HFSS and Microwave CST studio simulation software, was also realized, and return loss measurements were taken for the on/off states of the diode. While the proposed antenna shows a single bant resonance in the WiMAX band in the off state of the diode, it resonates in the 2.4 and 5.2 GHz WLAN bands in the on state. In addition, the realized gain values of the antenna, which exhibits very uniform radiation characteristics in the relevant frequency bands for the E and H-planes, are between 2-4 dBi.

Abstract

Bu çalışmada, WLAN ve WiMAX uygulamaları için elektriksel olarak frekansı ayarlanabilir yeni bir düzlemsel evrilmiş-F anten (DEFA) tasarımı önerilmektedir. 30 × 25 × 10 mm3 boyutlarındaki antenin ana radyatörü simetrik olmayan kıvrımlı şerit elemanlarından oluşmakta ve frekans cevabı bu elemanlar arasında optimum konumda kullanılan bir PIN diyotu aracılığıyla dinamik olarak ayarlanabilmektedir. Sayısal tasarımı Ansoft-HFSS ve CST Microwave Studio benzetim yazılımları aracılığıyla gerçekleştirilen antenin prototip üretimi de gerçeklenerek, diyotun açık/kapalı durumları için geri dönüş kaybı ölçümleri alınmıştır. Önerilen anten diyotun kesim durumunda WiMAX bandında tek bent rezonans gösterirken, iletim durumunda 2.4 ve 5.2 GHz WLAN bantlarında rezonansa gelmektedir. Ayrıca E ve H-düzlemleri için ilgili frekans bantlarında oldukça düzgün ışıma karakteristikleri sergileyen antenin mutlak kazanç değerleri 2-4 dBi arasındadır.
