A compact offset coplanar waveguide (CPW)-fed dual polarized stubs loaded L-shaped branch monopole antenna for quad-band operation is presented. A resonant mode at 2.48 GHz is generated by adding an inverted L-shaped branch in the offset CPW-fed monopole and other three resonant modes at 3.41/4.96/7.45 GHz are generated by integrating asymmetrical long/middle/asymmetrical inverted short L-shaped stubs...
A compact coplanar waveguide (CPW)-fed F-shaped stub printed antenna is presented. The first and second resonance modes are excited due to F-shaped stub connected to modified CPW ground plane and third resonance mode due to modified L-shaped CPW feeding. The impedance bandwidths of 190 MHz (2.06–2.25 GHz) for UMTS band, 530 MHz (4.61–5.14 GHz) for 4.9 GHz public safety WLAN, 1490 MHz (5.45–6.94 GHz)...
A design of compact multi band circularly polarized asymmetrical fractal boundary microstrip patch antenna with DGS (defected ground structure) and fractal boundary techniques has been proposed. Using the DGS technique a cross slot and circle are cut away at the centre of the ground plane to enhance the single band to multi band. The structure is asymmetrical along to the principal axes (x, y) because...
A design of dual wide band circularly polarized circular patch with parasitic ring and defected ground structure. By using the coaxial probe feed 45° with respect to the axis of the two stub plane of the patch then excellent circular polarization (CP) is achieved. The antenna is designed with a double-layer structure, comprising a circular patch with two rectangular stubs along the diameter direction...
A wideband micro strip patch antenna is designed for satellite communication. It achieves multi-band functionality through the array technique. The proposed antenna generates circular polarization and good radiation efficiency. The implementation of array technique provides better efficiency. It is a 2×3 array pattern with Microstrip line feed. It operates about C and X bands efficiently.
