A compact tri-band, low profile, and lightweight antenna is proposed for 2.4/5 GHz WLAN Ku-band applications. The geometry was a radiating rectangular patch surrounded by wide circular slot with an inverted-L strip connected to one side of the slot. It mounted on copper layer single FR4 substrate dielectric constant 4.3 height 1.6 mm. fed 50-Ω coplanar waveguide. This design very (40 × 40 mm3)....

A printed slot antenna fed by a microstrip line with a diamond-shaped tuning stub for bandwidth enhancement is proposed and experimentally validated. Impedance bandwidth, radiation pattern, and gain characteristics of the proposed antenna are investigated. The simulated results show that the impedance matching of the proposed rotated slot antenna is greatly affected by the dimension of the slot...

This paper shows a comparative study of Multi U–shaped slot antenna with the substrate integrated waveguide(SIW) fed patch antenna. By cutting four asymmetrical U-slots, we can make U-shaped patch antenna. Advantages of this structure are the simple feed, single layer structure, simple structure of antenna, one more degree of freedom can be achieved by the asymmetry of U-slot arm. The design gu...

In order to improve the bandwidth of the traditional patch antenna, a new antenna sensor based on the U-slot antenna was designed in this paper. The electromagnetic simulation software Ansys-HFSS was used to analyze the impact of the antenna parameters, and short circuit loaded half U-slot antenna with a slot ground plane was designed at last. The main bandwidth of the antenna sensor ranges fro...

High gain broadband plasmonic slot nano-antenna has been considered. The theory of plasmonic slot nano-antenna (PSNA) has been developed. The analytical model takes into account also the electrical field inside the metal due to imperfectness of metal in optical range, as well as numerical investigation based on finite element method (FEM) has been realized. It should be mentioned that Yagi-Uda ...
