Patch Antenna With Reconfigurable Polarization

A Fabrication of Intelligent Spiral Reconfigurable Beam Forming Antenna for 2.35-2.39 GHZ Applications and Path Loss Measurements

“…In [10], a beam covering off −70 • to +70 • has been achieved via a reconfigurable thin substrate antenna. A composite right/left-handed (CRLH) waveguide implemented in a substrate integrated waveguide (SIW) configuration is designed in [11] To the authors' knowledge, none of the beam steering antennas achieved maximum beam at all beam steered direction [12][13][14][15]. In [13], a multi-feed dielectric resonator antenna has achieved beam steering of H-plane at 0 • and 270 • with peak gain of not exceed 2 dBi.…”

Planar Bowtie Antenna With a Reconfigurable Radiation Pattern

“…Accordingly, in the last years several approaches for the design of antennas providing diversity functions in operating frequency [1,2,6], polarization [3][4][5] and radiation pattern [1,[5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] have been proposed. Among them, antennas able to modify their radiation pattern while preserving the working frequency and polarization are key components for improving the performance and security of MIMO (Multiple-InputMultiple-Output) architectures [5,9].…”

Fractal-Shaped Reconfigurable Antennas

“…13, respectively. Another type of printed antennas, which deals with both frequency and polarization reconfigurability, was reported by (Monti et al, 2009). The proposed design approach, illustrated in Fig.…”

“…A low-cost multiband printed-circuit-board (PCB) antenna that employs Koch fractal geometry and tunability was demonstrated by . In their work, the authors combined the space-filling property of Koch fractal with reconfigurability in order to a multiband/wideband operation with the antenna (Monti et al, 2009) still compact in size. A prototype of the fabricated design along with its return loss plot, for three switching conditions, is shown in Fig.…”
