This paper presents an investigation of split ring resonator (SRR) parameters on a coaxial-fed monopole antenna. The adding of SRR slot can create a notch in the result of coaxial-fed monopole antenna design. Thus, this paper aims to investigate the effect of changes to the outer ring radius and slit cut width of the SRR slot. All antenna designs and simulations involved are drawn and simulated...

A compact rectangular slot antenna with single wide band-notched characteristics is proposed. This co-planar waveguide (CPW) fed antenna is suitable for ultra wide band (UWB), X-, Kuand K-band applications. The patch of the antenna is a modified rectangular slot with T-stub structure in an elliptical slot etched in the radiating patch. This T-stub structure creates wide band notched at WLAN and...

An Ultrawideband (UWB) high gain compact Vivaldi antenna with end fire radiation patterns is presented for radar and microwave imaging applications. The antenna is operating for 2.9GHz to more than 11GHz with -10dB impedance bandwidth and is designed on low cost FR4 substrate of thickness 0.8mm. While designing the proposed antenna, initially a compact exponential tapered slot Vivaldi antenna i...

Hepatocellular carcinoma (HCC) is the most common malignant tumors to affect the liver. Microwave ablation is efficiently used for treatment of liver cancer. Although surgical resection remains the gold standard for treatment of liver cancer, but only 5-10% patients are the candidates for surgical resection due to numbers of limitations. Because most patients with HCC can not be treated with su...

A circularly polarized single feed microstrip slot antenna has been introduced in this paper as a candidate for use in GPS applications. The slot structure of the proposed antenna has been created on the radiating patch in two steps. At first, a 45 degree rotated square has been etched at the center of the patch, and then a Sierpinski gasket type of the 3rd iteration occupies the resulting slot...

In this paper, two single rectangular patch antennas with a slot are designed and analyzed theoretically from the concept of multi-cavity structure. The theoretical return loss parameters of the antenna electrical characteristics are in good concordance with the advanced design system (ADS) simulation. Two patch antennas with rectangular slot are designed in two different geometries relatively ...

In this paper, a hybrid dual-band cylindrical dielectric resonator antenna with parasitic slot fed by a microstrip line that is suitable for wireless body area network is proposed. In this configuration, the dielectric resonator performs the functions of an effective radiator along with the feeding structure and the slot in the ground plane. By optimizing the structural parameters, the antenna ...

This paper provides experimental and implementation details for various forms of multiple-input multiple-output (MIMO) cube antennas. Slot dipole antennas are used as basic elements of these MIMO antennas. Experimental results show that especially at higher frequencies of various wireless applications the additional loss of the printed antennas increase and therefore implementation of such ante...

Kyungho Chung et al. 379 ABSTRACT⎯A novel reconfigurable microstrip patch antenna with frequency and polarization diversities is proposed. A U-slot is incorporated into a square patch, and a PIN diode is utilized to switch the slot on and off, which realizes the frequency diversity characteristic. The polarization diversities among linear polarization (LP), right-hand circular polarization (RHC...

A novel design of a CPW fed printed monopole antenna for dual polarization applications is proposed in this paper. The monopole is formed of a rectangular patch embedded with a hour-glass shaped slot. In a modified version of the antenna, an additional spiral shaped slot is incorporated in the ground plane. The overall dimensions of the antenna are kept at 40× 40mm. The impedance bandwidth achi...
