This work presents a planar antenna for Ultra-HighFrequency (UHF) Radio Frequency Identification (RFID) Tags to be applied on metallic surfaces. The proposed radiating structure consists of a short-circuited patch antenna designed with a fractal geometry, resulting in a very compact and cost effective Tag. Showing a very good platform tolerance, such a Tag is also suitable for application on di...

The hasty growth of wireless technologies has drawn new demands for integrated components including antennas and antenna on chip is a new mantra in the area of antenna research. Various techniques have been suggested by researchers for the miniaturization of microstrip patch antennas with multiband characteristics. Numerous antennas for multiband operation have been studied and designed for com...

In this paper, the optical properties of one dimensional fractal structures are investigated. We consider six typical fractal photonic structures: the symmetric dual cantor-like fractal structure, the asymmetric dual cantor-like fractal structure, the single cantor-like fractal structure, the symmetric dual golden-section fractal structure, the asymmetric dual golden-section fractal structure a...

This paper presents a multiband slot antenna with modifying fractal geometry fed by coplanar waveguide (CPW) transmission line. The presented antenna has been designed by modifying an inner fractal patch of the antenna to operate at multiple resonant frequencies, which effectively supports the digital communication system (DCS 1.71–1.88 GHz), worldwide interoperability for microwave access (WiM...

Based on the study of Digital Elevation Simplification Model and fractal theory, this paper put forward a new method to simulate complex terrain. That use simplified DEM data to construct terrain frame based on the quad tree at first, and then use fractal to generate the details of every node of the tree. In the process of construction, the LOD theory is used to simplify the terrain and get its...

In this paper, a coplanar waveguide (CPW) fed slot antenna using fractal-shaped isosceles trapezoidal corrugations is designed and presented for Ultra-Wideband (UWB) applications. The proposed formed by regular hexagonal patch through CPW feed line radiates amidst notched wide slot. edge of the shaped fractal structure that five notches. printed on RO4350B substrate having compact size 0.305λ0 ...

This paper introduces the design of a dual-band internal F-PIFA (Fractal Planar Inverted F-antenna) as a candidate for use in the dual band WLAN (wireless local area network) MIMO (multi-input multi-output) applications. At first, the 4th iteration Koch’s fractal geometry has been applied to the edges of the conventional rectangular patch structure to design a single compact antenna with a dual...

This paper presents the design of a wheel shaped multiband fractal Antenna. This Fractal antenna has been designed on substrate εr = 4.3 and thickness h = 1.53 mm. This new antenna has been fed with CPW – Fed. The antenna exhibits the multiband resonances due to selfsimilarity in antenna structure. The experimental results indicate that resonant frequencies occur at 1.34 GHz, 2.575 GHz, 4.22 GH...
