This article briefly reviews broadband design techniques in dielectric resonator antennas (DRAs). The attentions focus on a type of DRAs that can offer multi-resonant frequencies and these frequencies can be mergered into a broad band. Index Terms dielectric resonator antenna, broadband, multi-frequencies.1

The paper presents results from the first SUITED (multi-segment System for broadband Ubiquitous access to InTErnet services and Demonstrator) demonstration campaign, focusing on the GMBS (Global Mobile Broadband System) terminal. A practical user mobility solution for a heterogeneous access network and a trial realisation is described. A new vehicular satellite active antenna concept, developed...

Abstract High speed data transmissions are required for the next generation mobile communication systems. However, broadband mobile channel is composed of many propagation paths with different time delays, producing severe frequency-selective fading channel. Recently, multi-carrier code division multiple access (MC-CDMA) has been attracting much attention for the broadband wireless access in th...

In wireless communication a broadband signaling method is one that handles a wideband of frequencies. The wider the bandwidth of a channel, the greater the information carrying capacity given the same channel quality. At present there is increase in demand for several wireless applications which increases the number of antennas per system typical antennas are designed for specific narrowband of...

Antenna (subset) selection techniques are feasible to reduce the hardware complexity of multiple-input multiple-output (MIMO) systems, while keeping the benefits of higher-order MIMO systems. Many studies of antenna selection schemes are based on frequency-flat channel models, which are inconsistent to broadband MIMO systems employing spatial-multiplexing. In broadband MIMO systems aiming to pr...

Mobile broadband communication is experiencing rapid growth in technology, markets and range of services. This rapid growth has driven the recent surge of research and development activities for high-data-rate/high-mobility wireless systems, with improved network performance and enhanced economics. One technology thrust in wireless communications is the use of adaptive antennas at the transceiv...

This paper proposed a novel broadband Planar Inverted-F Antenna(PIFA) for IMT-2000/WLAN/DMB terminal. Two branch lines for meander line were utilized in order to improve the characteristics of PIFA which usually has a narrow band. The shorting strip between the ground plane and meander-type radiation elements were used in order to minimize the size of the antenna. The −10dB return loss bandwidt...

We present a new reconfigurable broadband miniature antenna architecture that is able to change its working frequency, polarization, or radiation pattern to get single broadband or dualband behavior for a single widebeam or multibeam diversity configuration. First the basic so-called “dime” geometry is introduced. Numerical and experimental results for a prototype at 5.2 GHz are presented. Base...
