A Simple and Effective Approach for Scattering Suppression in Multiband Base Station Antennas
نویسندگان
چکیده
The high band pattern distortions in an 1810–2690 MHz frequency band, introduced due to low radiators working 690–960 MHz, are mitigated by a simple yet effective change the band-radiating elements. A novel horizontal and vertical radiating element is designed instead of conventional slant polarized reduce scattering. polarization achieved from dipoles, using 180° hybrid coupler. dipole length optimized improve patterns. experimental results verified that proposed result reduction distortions. elements provide >12 dB return loss over entire comparable performance dipole.

this study intends to investigate samuel beckett’s waiting for godot and endgame under the lacanian psychoanalysis. it begins by explaining the most important concepts of lacanian psychoanalysis. the beckettian characters are studied regarding their state of unconscious, and not the state of consciousness as is common in most beckett studies. according to lacan, language plays the sole role in ...
Measurement and Computational Modeling of Radio-Frequency Electromagnetic Power Density Around GSM Base Transceiver Station Antennas
Evaluating the power densities emitted by GSM1800 and GSM900 BTS antennas isconducted via two methods. Measurements are carried out in half a square meter grids around twoantennas. CST Microwave STUDIO software is employed to estimate the power densities in order fordetailed antenna and tower modeling and simulation of power density. Finally, measurements obtainedfrom computational and experime...
متن کاملA Base Station Centralized Simple Clustering Protocol for Sensor Networks
Sensor nodes in wireless sensor network are severely energyconstrained. This has been a key factor to limit its performance. So far, many energy-efficient routing protocols have been proposed. Clusterbased routing protocols have been paid much attention because of their advantages. However, the cluster-based routing protocols require information on the locations of the sensor nodes in the netwo...
متن کاملNear Field in the Vicinity of Wireless Base-Station Antennas: An Exposure Compliance Approach
Great social concern has risen about the potential health hazard of living near a cellular telephony base-station antenna, and certain technical questions have been posed on the appropriate way to measure exposure in its vicinity. In this paper, standard spherical near–near field transformation is proposed to obtain the electromagnetic field close to the antenna in free space conditions. The fi...
متن کاملMultiband Fractal-like Antennas
Abstract—In this paper, new multiband fractal-like antennas are proposed. The proposed multiband antenna design is based on a methodology that utilizes the self transformation principle of fractallike rectangular profiles to generate multiband operation. The proposed monopole-type antennas are built on a partial ground plane and fed through a microstrip feed line. The analytical design procedur...
