In this paper, a reconfigurable patch antenna design operating at 868MHz for Low Power Wide Area Network (LoRa), 1.58 GHz for Global Positioning System (GPS) and 2.4 GHz for Bluetooth is presented. The design is reconfigurable thanks to the …
This paper addresses the design and measurement of an implantable RFID tag for small animal monitoring applications. In particular, the design of a miniature printed dipole antenna and its integration with a commercial RFID transceiver is discussed. …
The uniplanar compact photonic bandgap (UC-PBG) metamaterial structure has been profitably used for antenna miniaturization and radiation enhancement purposes. This paper presents an additional way to exploit it, when it is employed as ground plane …
In this paper an antenna array for imaging applications is presented. A two-step design process is used. In the first step, a wideband printed monopole antenna to be employed as the array element is synthesized by means of a Particle Swarm …
In this letter, a dual-band fractal monopole antenna suitable for Long Term Evolution (LTE) standard is proposed. The antenna geometry is based on a perturbed planar Sierpinski fractal shape, whose geometrical descriptors are determined by means of a …
In this letter, a spline-shaped ultrawideband (UWB) antenna enabling simultaneous operability over multiple mobile wireless standards-namely the DCS, PCS, UMTS, and ISM bands-is proposed. The antenna is expected to exhibit a good impedance matching …
In this letter, the design of a quad-band antenna is presented. The antenna has a planar geometry printed on a dielectric substrate orthogonal to a reference ground plane and its geometrical parameters are optimized starting from a Hilbert-like …
In this paper, an innovative spline-based approach for the UWB antennas synthesis has been proposed. The flexibility and accuracy of the method allows a reliable matching of UWB requirements. A representative design example described through the …
This letter presents the design of a planar antenna for ultrawideband (UWB) applications with a bandwidth of 5.5 GHz over 3.7 to 9.2 GHz and return loss values lower than -10 dB. The antenna geometry is described in terms of a spline-based …
