These days, microstrip antennas are preferred in many areas of wireless communication, due to their advantages
such as low volume coverage, light weight, surface compatibility, high cost requirements and easy production
etc. Also microstrip antennas have these advantages as well as disadvantages such as low gain, low power
operation and narrow bandwidth etc. The main disadvantages of these antennas are their narrow band
performance (~10). In this study, a classical wideband microstrip dipole antenna design which can be used in WLAN/WiMAX
applications (covering the bands 2.4–2.5 GHz and 2.5–3.5 GHz) is introduced. Proposed antenna design has a
frequency bandwidth of 43% and performs at 2.363.67 GHz. Note that |S11| ≤ 10 dB criterion with 50
system impedance is considered. Antenna design has a non-directional radiation pattern with a gain of 2.36 dBi
and with a total efficiency of -0.428 dB. In this report, numerical analyses results of the design are obtained by
using CST Microwave Studio. Also a number of parametric studies have been carried out to show the parameters
which affect the performance of the proposed antenna design.
Mikroşerit antenler az hacim
kaplamaları, hafif ve yüzeye uyumlu olmaları, fazla maliyet gerektirmemeleri,
üretimlerinin kolay olması gibi avantajları nedeni ile günümüzde kablosuz
haberleşmenin her alanında sıklıkla tercih edilmektedirler. Bu yapıların en
büyük dezavantajları ise dar bantlı performans sergilemeleridir. Çalışmalarda
bu sorunu gidermek için anten geometrisi ile oynanarak veya antene yeni
eklemeler yapılarak daha geniş bantlı karakteristikler elde edilmiştir.
Literatürdeki geniş bantlı mikroşerit tasarımlar incelendiğinde, klasik
mikroşerit dipol antenlerin bu uygulamalar için pek tercih edilmedikleri
görülmektedir.
