“…This design exhibits end-fire characteristics [15] and E-shaped dual-band antennas with defective ground structures for enhanced performance [16]. Other research has focused on optimizing antennas for the widely used Wi-Fi frequency bands of 2.4 GHz and 5 GHz, utilizing microstrip lines and low-cost materials for cost-effective production [17]. Additionally, the integration of complementary split ring resonators (CSRR) has enabled compact antennas to achieve dual-band operate at 5.8 GHz and 7.1 GHz, suitable for Wi-Fi and C-band applications [18].…”

This research presents an innovative dual-band microstrip patch antenna design enhanced with defected ground structures (DGS) and barium strontium titanate (BST) thin film, tailored for wireless local area network (WLAN) and WiMax applications. The first design phase involved the development of an microstrip patch antenna (MPA) using an flame retardant (FR4) substrate with a permittivity (εr1) of 4.3 and a thickness of 1.524 mm, enhanced with DGS. This configuration achieved a single-band resonance at 4.1 GHz, with a bandwidth of 0.82 GHz and a return loss (S11) of -32 dB. The second phase involved the integration of a BST thin film, with a high permittivity(εr2) of 250 and a thickoness of 0.1 mm, into the DGS-enhanced microstrip patch antenna (MPA). This mdification led to a transformation in the antenna's performance, enabling dual-band operation at resonance frequencies of 2.8 GHz and 5.8 GHz. Further, there was a corresponding substantial increase in bandwidth to 1.34 GHz and 1.25 GHz, respectively, an improvement in S11 values to -16.3 dB and -21.4 dB. Moreover, and antenna’s size of 14×10×1.524 mm<sup>3</sup> . The study underscores the critical role of innovative material use and design optimization in advancing antenna technology, offering significant enhancements in bandwidth, and miniaturization, for wireless communication systems.

Çalışma frekansının farklı olduğu bu Wi-Fi modullerinin kapsama alanları bir evin içerisindeki konumu ve odaların duvarlarının özellikleri çeşitli parametrelere bağlı olarak değişmektedir. Kapsama alanlarının üzerinde bu parametrelerin etkisinin araştırılması için bir ev tasarlanmış ve ev içerisindeki 3 farklı konum için odalara 2.4 GHz ve 5 GHz yayın yapan antenler içeren modemler yerleştirilmiştir. Ayrıca duvarların kalınlığı ve duvarın yapıldığı malzemenin kapsama alanına etkisi incelenmiştir. Analizler gerçekleştirilmeden önce 2.4 GHz ve 5 GHz frekansındaki monopol antenler için uzak alan ışıması elde edilmiş ve sonrasında elde edilen uzak alan ışıma verileriyle konut içerisindeki ışıma analizi gerçekleştirilmiştir. Yapılan analizler ve kıyaslamalar sonucunda 2.4 GHz modemin 5 GHz modeme göre daha fazla kapsama alanı sağladığı tespit edilmiş ve ayrıca, ahşap özellikli duvarın en iyi kapsama alanını sağladığı gözlemlenmiştir.

In this paper, two novel compact low-profile dual-band plasmonic antennas designed with the help of Characteristic Mode Analysis and parametric study are presented. The plasmonic antennas contain microstrip line-fed strip-loaded patches and partial ground planes. The final proposed antennas cover the two bands in the frequency range of 2.4-2.5 GHz and 5-6 GHz. Plasmonic antennas offer nearly omnidirectional patterns at the desired frequency ranges. Additionally, a detailed parametric study of almost all the design parameters is performed to display the effect of varying those parameters on the resonance frequency at both bands. The parametric study for both antennas has been carried out to optimize the antenna and get better-enhanced results. The antenna is also fabricated and measured results are obtained. The comparison of results shows a good similarity between the simulated and measured results. The designed antenna can be applicable for 5G/ WiFi/WLAN applications.
