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)...
Proposed coplanar waveguide (CPW) fed meta-material antenna is also one of them to invoke the multiband applications in the frequency range of 5.4–5.8GHz. Meta-materials are capable to manipulate EM waves by blocking, absorbing, enhancing, and bending waves and also radiate more energy. The proposed antenna having the hairpin structure is designed with FR4 substrate having permittivity of 4.4 and...
Proposed CPW-fed meta-material inspired antenna is also one of them to invoke the WLAN and Wi-MAX applications in the frequency range of 5.4–5.8GHz. Meta-materials are capable to manipulate EM waves by blocking, absorbing, enhancing, and bending waves and also radiate more energy. The proposed antenna having the rectangular structure (tilted E-S shaped) designed by using FR4 substrate having dielectric...
In this paper, the CPW fed Z monopole antennas has proposed for Industrial, Scientific, and Medical (ISM) band (2.4–2.48 GHz) applications. To make the designed antenna suitable for implantation, it is printed on biocompatible Al2O3 ceramic substrate. The antenna was simulated by immersing it in a phantom liquid, imitating the electrical properties of the human muscle tissue. Simulations in various...
In this paper we propose a CPW fed U shaped reconfigurable antenna for cognitive radio application. The reconfigurability in frequency is obtained by connecting the switches in the basic antenna by use of pin diodes. By controlling the switches the antenna can be operated at different frequencies. The antenna is designed to resonate at different frequencies at UWB band and it is investigated by use...
In this work, an implantable coplanar waveguide (CPW) fed tapered monopole antenna for industrial scientific and medical (ISM) band (2.4 – 2.48 GHz) biomedical applications is proposed. This proposed design has an overall dimension of 44mm × 44mm × 0.5mm. The designed antenna is made compatible for implantation on human tissues like skin, fat or muscles by embedding it on RT Duroid substrate and the...
The proposed implantable CPW fed monopole slot antenna for industrial scientific and medical (ISM) band biomedical applications of dimension 25mm × 16mm × 0.5mm at ISM band (2.4 – 2.48 GHz) and short distance communication band (Electronic Communications Committee approved the frequency band 688 MHz). The antenna is placed on human tissues like skin, fat, muscle, etc and it is made compatible for...
A compact coplanar waveguide (CPW)-fed ultra-wideband printed circular monopole antenna with band-notch characteristics is presented in this paper. The proposed antenna consists of a split ring resonator (SRR) in the circular patch to achieve a band notched characteristics in the WLAN (5.15–5.825 GHz) band. The predicted VSWR, frequency notch behavior in VSWR, gain and radiation patterns are analyzed...
