In this paper, a novel “green” inkjet-printed antenna for UHF Radio Frequency Identification (RFID) tags is presented. A slotted Z-shaped monopole configuration is selected and fabricated using inkjet-printing technology on a flexible, low-cost paper substrate utilizing a simple, fast, and environmentally friendly process. The design characteristics of the antenna are verified and the simulated...

In this paper, the design and performance analysis of an Inkjet-printed metamaterial loaded monopole antenna is presented for wireless local area network (WLAN) worldwide interoperability microwave access (WiMAX) applications. The proposed structure consists two layers, one rectangular tuning fork-shaped antenna, another layer inkjet-printed superstate. designed using four split-ring resonators...

Anultra-wideband (UWB) bowl-shaped monopole antenna with a sturdy, simple, and lightweight structure is proposed, then used to compose the 3 × multiple input output (MIMO) antenna. The wide bandwidth determined by outline of monopole, which has quarter wavelength high-order modes. inner part removed for light weight. simulated measured results show that an ultra-wide band 2.3–8.1 GHz (5.8 GHz, ...

Abstract—A novel ultra wideband (UWB) multiple-input-multiple-output (MIMO) antenna with different polarizations and band-notch characteristics is proposed in this letter. The antenna consists of two monopole antenna radiating elements with gradual change structure, which are placed perpendicularly to each other and printed on each side of the substrate to achieve a wide bandwidth and different...

This paper presents a rectifying antenna (rectenna) for the harvesting of the microwave energy associated to UHF (UltraHigh Frequency) Radio Frequency IDentification (RFID) systems. The proposed device uses a capacitively loaded T-shaped monopole with a coplanar waveguide feeding line as receiving antenna and a five-stage voltage multiplier as rectifier. Experimental results demonstrating an RF...

A novel miniature antenna based on the fractal Hilbert geometry is presented. The antenna becomes electrically smaller as the fractal iteration increases at a higher rate than that of any other fractal geometry presented until now. Several fractal-shaped Hilbert monopoles have been constructed, measured, and compared with the classical /4 monopole. © 2003 Wiley Periodicals, Inc. Microwave Opt T...

In this paper, the design and implementation of plasma antenna array with beam forming is discussed. The structure consists of a circular array of plasma tube enclosed in a unipolar UHF band monopole antenna. Beam forming is possible by stimulated plasma tubes. The combination of the above antenna with plasma excitation controller makes a beam forming smart antenna. An experimental model in UHF...

This paper gives information about construction of planar rectangular monopole antenna on Printed Circuit Board (PCB). Behaviour of such planar antenna is same as the rectangular patch antenna with finite ground plane which lies in same plane of given PCB. The designed antenna is a broadband antenna as its ratio bandwidth falls under broadband category. In comparison with monopole antenna broad...
