The results of reduced- size cascaded Butler matrices developed for dual-band and dual-beam applications are presented in this paper. The meander-line technique, an acceptable approach for reducing the size of the radio ...
A reconfigurable WiMAX antenna for directional and broadside application
(Hindawi Publishing Corporation, 2013)
A novel reconfigurable compact patch array antenna for directional and broadside application is proposed. The presented antenna has successfully been able to function for directional beam at 320° or 35° and divisive broadside ...
Correlation analysis on UWB MIMO tree-antenna orientations
(Wiley Periodicals, Inc., 2013-03)
This research proposes a miniaturized antenna with a novel design for the ultra-wideband (UWB) multiple-input multiple-output (MIMO) system. The UWB-MIMO tree-antenna (UMTA) design consists of two symmetrical designs with ...
Frequency and pattern reconfigurable dipole-Yagi antenna
(Wiley Periodicals, Inc., 2013-02)
A novel dipole-Yagi antenna is presented with pattern and frequency reconfigurable capability. The novel structure is based from Yagi-Uda antenna, consist of dipole as a main radiator and four parasitic metal strips. The ...
Impact of spacing and number of elements on array factor
(The Electromagnetics Academy, 2012-03-27)
The impact of spacing and number of elements in terms of gain and half power beam-width (HPBW) are shown in this paper. The antenna's gain is depending on two parameters which are number of elements and element spacing. ...
Impact of number elements on array factor in linear arrays antenna
(Institute of Electrical and Electronics Engineers (IEEE), 2012-03-23)
The impact of number of elements on array factor
shown in this paper. The array factor of an antenna is been a
gain’s measurement. Therefore, a linear antenna will achieve a
good signal’s propagation when they have ...
