In this paper, a novel compact printed monopole antenna is presented. The consists of planar and tapered-line resonator with inner coupled section, which works as near-field resonant parasitic (NFRP) element. frequency can be decreased dramatically by the strong coupling between antenna. Thus, miniaturization realized. simulated results show that decreases from 2.98 GHz to 2.4 electric length r...

A single-band monopole antenna, transformed into a triple-band antenna for S-band and C-band applications is reported in this paper. This transformation done with the help of two different hybrid SRR unit cells, which are embedded on truncated ground plane antenna. These cells created by combining square split ring circular configurations. Simulated results coherence measured analysis provided ...

Miniaturization trends in high-frequency electronics have led to accommodation challenges the integration of corresponding components. Size reduction thereof has become a practical necessity. At same time, increasing performance demands imposed on electronic systems remain conflict with component miniaturization. On side, related handling design constraints are aggravated by high cost system ev...

Electrically small antennas are needed to further lower the cost of wireless elements. However, the antenna gain is constrained to the Harrington limit, while the impedance matching and directivity characteristics deteriorate in electrically small antennas. Using a dipole antenna loaded with a left-handed ladder structure is a promising technique for reducing the size of antennas. In this lette...

In this paper, Ultra wideband circular Microstrip patch antenna is proposed. Over years, great interest was focused on microstrip antennas for their small volumes, low profiles, good integration, low costs and good performance. With the continuous growth of wireless communication service and the constant miniaturization of communication equipment, there are higher and higher demands for the vol...

in this paper a new low profile substrate integrated waveguide (siw) probe-fed h-plane horn antenna structure with improved gain is proposed. the proposed antenna consists of two waveguides including a rectangular and a taper one, in which both, first and third modes of the structure are simultaneously excited leading to a uniform field distribution along the radiating aperture of the antenna a...

In this study, we propose a composite right/left-handed (CRLH) cuboid antenna operating in the very-high-frequency band. The proposed uses CRLH transmission-line structure for miniaturization, and left-handed component is implemented using interdigital capacitors meander lines. A three-dimensional was designed to increase parallel inductance by applying line side of structure. operates at 252.5...

Invasive and implantable biomedical devices used for diagnostic and therapy, ranging from neural prosthesis to video-capsule endoscopy (VCE) systems, are emerging innovative technologies and they are expected to originate significant business activity in the near future. The success of such systems is in part due to the advent of microtechnologies, which made possible the miniaturization of sev...
