A compact monopole antenna having wide bandwidth with multi-bands as well as dual polarization characteristics for wireless communication is presented. To get impedance matching for the SMA conductor, the antenna is fed up by Micro-strip feeding technique. In this, the antenna is embedded by an L-shaped slots on the ground plane, to improve the bandwidth by excited the addition of resonance. To...

Recently, antenna and its feed system in wireless communications require to be multifunctional for enhancing flexibility and feasibility, such as easy of integrate, low-profile, inexpensive and ease of fabrication, and wideband or multiband operating.The objective of the project is to design and develop a simple monopole antenna based on composite metamaterial resonators for multiband operation...

To suppress electromagnetic interference at 5.5-GHz WLAN (5.15–5.825 GHz) band operation, a novel ultra-wideband (UWB) design of a slotted twin-patch monopole antenna with a band-rejection characteristic is presented. The proposed antenna with a simple structure has a large impedance bandwidth, defined by 10-dB return loss, covering the range from 2.95 to 10.85GHz, and a tunable cutoff band fro...

A compact wide-slot antenna with microstrip-fed monopole for ultrawideband (UWB) application. The monopole is composed of an elliptic patch connected to a trapezoid one. The radiator patch is attached to a 50microstrip feed line by a smoothly tapered line to enhance the wideband matching. A hexagonal slot is etched from a finite ground plane placed on the other side of the substrate. The antenn...

According Tesla’s idea his magnifying transmitter has been designed not only to efficiently emit Hertzian waves, but also to transmit power at large distances. Analysis of Tesla's transmitter by using the wire antenna theory and reflection coefficient approximation is carried out in this work. The radiating part of the Tesla's transmitter is represented by an equivalent monopole antenna driven ...

Highly omnidirectional and frequency controllable carbon/polyaniline (C/PANI)-based, two- (2D) and three-dimensional (3D) monopole antennas were fabricated using screen-printing and a one-step, dimensionally confined hydrothermal strategy, respectively. Solvated C/PANI was synthesized by low-temperature interfacial polymerization, during which strong π-π interactions between graphene and the qu...
