The capacity of wireless CDMA systems in the forward link is limited by both intra-cell and inter-cell cochannel interferences. In particular, when the mobile is close to a cell boundary, the desired signal from home base station (BS) is disturbed by relatively strong interference from neighboring BSs. In this paper, a receiver architecture is suggested at the mobile to utilize ...

A two-dimensional beam steering array composed of an eight-element antenna array using composite right/left-handed leaky-wave antennas fed by an 8 × 8 Butler matrix network is designed at X-band. An eight-way beam switching in one direction by input port switching and a continuous beam steering in the other direction by frequency sweep are achieved. A wide range beam steering operation covering from –55 to +53 degrees by port switching and from –37 to +27 degrees by frequency sweep is demonstrated with the maximum gain of 9.2 dBi.
A continuum solution for the phase evolution of a coupled oscillator array with coupling delay, when one oscillator is step detuned in time, is derived from the discrete model solution previously published. From this Green's function a differential equation is derived for the Laplace transform of the phase dynamics. The solution of this differential equation is expressed as a sum of the eigenfunctions of the differential operator for a finite length array with one oscillator detuned. The dynamic behavior of the aperture phase for beam steering is obtained by superposing two of the Green's function solutions corresponding to antisymmetric excitation at each end of the array. The far zone beam steering behavior is obtained by summing the elemental radiated signals. Generalization to planar arrays appears to be straightforward. An alternative more flexible formulation suitable for early times is also presented.
The capacity of wireless CDMA systems in the forward link is limited by both intra-cell and inter-cell cochannel interferences. In particular, when the mobile is close to a cell boundary, the desired signal from home base station (BS) is disturbed by relatively strong interference from neighboring BSs. In this paper, a receiver architecture is suggested at the mobile to utilize a small two-antenna array for interference cancellation. Such a canceller works well only when the channel vector of desired signal is known. We use the identifying spreading codes (as in IS-95 for example) to provide an adaptive channel vector estimate, and control the beam steering weight, hence improving the system capacity.
Investigations are presented dealing with integrated substrate structures to excite and guide magnetostatic surface waves feeding a planar antenna array. An equivalent circuit model is utilized to describe surface wave feeding and radiation. It is shown that phase and amplitude distribution of the suggested integrated array can be controlled by simple methods. The amplitude results from the configuration of the surface wave transducers, whereas the phase of the individual radiation elements is tunable by applying an external magnetic bias field. 5 and 4-element arrays for S- and C-hand, resp., are realized and scan angles up to<tex>\pm45\deg</tex>have been achieved.
A new bi-directionally steering phased array antenna controlled by dual piezoelectric transducers (PET) is presented. This phased array antenna operates over the frequency range from 7.6 to 26.5 GHz with a maximum beam scanning of 60/spl deg/ from -34/spl deg/ to +26/spl deg/. Both PET phase shifters are controlled by a single bias voltage that varies from 0 to 40 V. The PET controlled phase shifter is optimized with a parametric analysis, which results in a smaller control voltage and a better linearity of phase shift as a function of frequency, compared to the previously reported results. The proposed beam steering method should reduce the size and cost of phased array antenna systems.
The orbital angular momentum (OAM) carrying beams associated with helical wavefronts can be viewed as a complete set of eigen-modes for the electromagnetic waves, thus can be used to realize the structured radio wavefront with desired intensity and phase distribution. The structured radio beam maintains the vorticity and orthogonality of the OAM modes and has a directional gain. The unique characteristics provided by structured radio beam may afford a new solution to radar detection.
This paper presents a single aperture multibeam spatial power combining system that can support two separate polarizations. A Rotman lens is used as the power dividing network, which also has the ability to scan the beam over discrete angles. 1/spl times/9 dual polarized array was designed to demonstrate the beam steering in azimuth plane. The entire system is designed for the Ka band, with a center frequency of 32.5 GHz. The use of MMIC amplifiers allow for high power multibeam capabilities. Through simulations and measurements, a /spl plusmn/30 degree scan range was achieved for the horizontal and vertical polarizations.
The coaxial annular aperture structure is applied in this paper to construct multi-layer phase-gradient metasurfaces with high transmission efficiency realizing anonymous beam steering at 35GHz. Simulation results confirm that normally incident plane wave is successfully refracted by 19° and 60°, which are in good agreement with the theoretical design by the generalized Snell's law.
