A COMPACT AND MULTIBAND FRACTAL-INSPIRED PLANAR DIPOLE ANTENNA LOADED WITH SERIES CAPACITANCES AND A PARASITIC ELEMENT

A Wideband Planar Dipole Antenna with Parasitic Patches

Abstract—This paper presents a novel wideband planar dipole antenna with parasitic patches. Of which, acting primarily as directors, the parasitic elements aim to improve the radiation patterns in terms of gain especially at the higher frequencies. For verification, the proposed novel structure was fabricated and measured. The proposed antenna is well-matched with achieved VSWR < 2 and has a go...

Compact multiband Planar Inverted F Antenna (PIFA)

A compact stacked Quasi-fractal microstrip antenna for RFID applications

In this paper, we propose a new compact quasi-fractal shaped microstrip antenna that consists of a hexagonal patch as the main radiator and a complementary stacked patch as the parasitic element. The overall surface of the proposed quasi-fractal patch is about 55% lower than the conventional hexagonal patch. Using of stacked technique, the gain reduction of compression technique is almost compe...

A Comparison of Minkowski, Compact Multiband and Microstrip Fractals with Meander Fractal Antenna

This paper presents the comparison of existing fractal antennas with the proposed fractal antenna on the basis of performance parameters such as return loss and gain. Proposed antenna is designed on FR4 glass epoxy substrate with thickness 1.6mm and dielectric constant 4.4. The HFSS V13 software is used to design and simulate the proposed fractal antenna. By observing the simulated results of p...

A Wideband Circularly Polarized Slot-Loaded Dipole Antenna with L-Shaped Arms and Parasitic Patches

In this paper, a broadband circularly polarized (CP) antenna based on slot-loaded dipole with L-shaped arms and parasitic patches is proposed and investigated. Circular polarization is initially obtained at the lower frequency by bending the dipole arms into L-shape. To extend the axial ratio (AR) bandwidth, two pairs of parasitic patches are introduced along the orthogonal sections of the L-sh...
