An internal triple-band antenna fed by a microstrip line is proposed for operating PCS, IMT-2000, and Bluetooth bands. By using the two branchs of meander line, the desired resonant frequencies can be achieved. A broadband characteristic for each band is optimized by tunning the parts of radiating patch and size of each strip line segments. The proposed antenna and substrate are small enough to...

This invited paper details some of the hardware modelling and impairment analysis carried out in the EU mmMAGIC project. The modelling work includes handset and Access Point antenna arrays, where specific millimeter-wave challenges are addressed. In power amplifier related analysis, statistical and behavioural modelling approaches are discussed. Phase Noise, regarded as a main impairment in mil...

The diversity performance of the modurated scattering array antenna (MSAA) with various array spacing is measured in Rayleigh fading environment to investigate experimentally the relation between the array spacing and the diversity performance of the MSAA. A 2-element modulated scattering monopole array antenna with various array spacing which is supposed to be used for mobile handset applicati...

For mobile users without antenna arrays, transmission diversity can be achieved with cooperative transmissions, or by multi-branch system which uses the relays reached by the transmitter. When there is only one relay that can be reached by the transmitter, the transmission diversity can be obtained by a multi-hop system, then we emulate the (2 transmit antennas, 2 receive antennas) cooperative ...

Abstract − We measured the elevation angle distribution and cross-polarization power ratio of the incident power at the mobile station in different radio propagation environments at 2.15 GHz frequency. A novel measurement technique was utilized, based on a wideband channel sounder and a spherical dualpolarized antenna array at the receiver. Data was collected along over 9 km of continuous measu...
