A novel monopulse antenna for a tracking radar system is proposed using the time modulated antenna array technique. The time modulation technique applied in the antenna arrays overcomes the usual need for compromise between sum and difference beams and avoids the need for implementation of two separ

Abstract
In this paper, the directivity and gain of several types of timeโmodulated linear antenna arrays are obtained. Three types of array elements are considered: arrays with isotropic elements, parallel short dipoles, and collinear short dipoles. Curves of directivity as functions of interโelement spacing and sidelobe levels (SLLs) are presented. A comparison between the computed and measured gains of a timeโmodulated printed dipole linear array shows reasonable agreement. ยฉ 2004 Wiley Periodicals, Inc.

## Abstract In this paper, time modulation is applied to a small number of elements of a linear array that radiates either sum or difference patterns, in order to take control over their sidelobe levels. The simulated annealing (SA) technique helps to obtain the optimum time pulses applied to such
## Abstract This article presents the performance analysis of the multipleโinputโmultipleโoutput antenna systems for mobile WiMAX handset applications. To investigate the effect of changing antenna arrangements on the antenna performance, we propose four kinds of two antenna structures considering
This paper discusses the problem of direction-of-arrival (DOA) estimation for Gaussian sources that have arbitrary correlation: from independent to fully correlated. For independent sources, the antenna array design is governed by two competing considerations: maximum aperture, which inclines toward
