Abstract:

Harmonic suppressed fractal antenna with switches named TMFDB25 is developed to select desired frequency band from 400 MHz to 3.5 GHz. The radiating element length is changed to tune the operating frequency while the stub is used to eliminate the undesired harmonic frequency. The balun circuit is reduced by 75% from the original size. The antenna is built on a low loss material. It has the ability to select a single frequency out of fifteen different bands and maintain the omnidirectional radiation pattern properties. Furthermore, the antenna is designed, built, and tested.

Abstract:

Abstract A four-port multi-operational antenna system is designed for Cognitive Radio application. It consists of a sensing ultra-wideband antenna and three communicating narrowband antenna. The CPW fed monopole is a sensing antenna. It covers 2-11 GHz of the UWB band. The three narrow band antennas are operating at 5.834 GHz, 6.42 GHz, 7.355 GHz, and 8.786 GHz respectively. The mutual coupling is below-15 dB. This integrated UWB/NB antenna system can also be a good candidate for C-band, Maritime radio navigation, and X-band applications.

Abstract:

A single-port uniplanar antenna with a built-in tunable filter is presented for operation in multiple LTE bands for cognitive femtocell applications. The antenna is based on a monopole microstrip patch fed by coplanar waveguide. The frequency reconfigurability is achieved by using two PIN diodes to couple or decouple a ring slot resonator filter from the antenna feed line. By switching the PIN diodes, the proposed design can operate in either wideband or narrowband modes. When the antenna operates in the narrowband state, two varactor diodes are used to continuously tune the narrowband frequen

Abstract:

Proper narrowband antenna design for wearable devices in the biomedical application is a significant field of research interest. In this work, defected ground structure-based microstrip patch antenna has been proposed that can work for narrowband applications. The proposed antenna works exactly for a single channel of ISM band. The resonant frequency of the antenna is 2.45 GHz with a return loss of around -30 dB. The -10dB impedance bandwidth of the antenna is 20 MHz (2.442-2.462 GHz), which is the bandwidth of channel 9 in ISM band. The antenna has achieved a high gain of 7.04 dBi with an inc

Abstract:

It is very well known that the Rectangular Microstrip Antennas (RMA) are narrowband, but it is possible to enhance its bandwidth by cutting slots inside the patch. Some slots variations have been used to improve this important feature in modern mobile radiocommunication systems. U-slot antennas are employed in broadband applications, but it is very important to consider the usage of a thick substrate with a low dielectric constant. In this paper, an U-slot RMA built in a The Printed Circuit Board (PCB) with a thin FR4 substrate for 800 MHz to 900 MHz is presented and analyzed. The PCB that is

Abstract:

Ultrawideband (UWB) antennas are widely used as core devices in high-speed wireless communication. A novel compact UWB monopole antenna with an additional narrow band for Wi-Fi applications comprising a metamaterial (MTM) is proposed in this paper. The antenna has a compact size of 27 × 33 mm2 and consists of a V-shaped slot with two rectangular slots in the radiation patch. The inductance and capacitance develop due to the V-shaped slot in the radiation patch. The proposed antenna has −10 dB bandwidths of 3.2 GHz to 14 GHz for UWB and 2.38 GHz to 2.57 GHz for narrowband, corresponding to 144%

Abstract:

An ability of lensless titanium-based antenna coupled microbolometers (Ti-μbolometers) operating at room temperature to monitor precisely radiation patterns in terahertz time-domain spectroscopy (THz-TDS) systems are demonstrated. To provide comprehensive picture, two different THz-TDS systems and Ti-μbolometers coupled with three different antennas—narrowband dipole antennas for 0.3 THz, 0.7 THz and a log-periodic antenna for wideband detection—were selected for experiments. Radiation patterns, spatial beam profiles and explicit beam evolution along the propagation axis are investigated; pola

Abstract:

As the usage of wireless communicative devices is multiplying day by day, the need for the occupiable radio spectrum is also increasing. The inefficiency in the exploration of available licensed radio spectrum has rerouted the focus to effectively use it against the increasing demand. One of the available methods is to implement Cognitive Radio (CR) technology. The Cognitive Radio uses 2 antennas at a time in order to scan and to communicate with the available spectrum. While an Ultrawideband (UWB) antenna scans the spectrum for unused bands of frequencies, Narrowband (NB) antennas communicate
