Optimization of a Wideband Tapped-Delay Line Array Antenna

In this paper, an optimal approach to design wideband tapped-delay line (TDL) array antenna is proposed. This approach lets us control the array angular and frequency response over a wide frequency band. To this end, some design restrictions are defined and a multi-objective optimization problem is constructed by putting the individual restrictions together. The optimal weights of the TDL proce...

Parametric analysis of a broadband Archimedean spiral antenna with cavity

In this article an Archimedean spiral antenna is designed and analyzed that has good operation in broadband application. By analyzing this design, the effects that different parameters have on antenna operation will be studied and ways of optimization will be found.  Influences of cavity height and number of turns to obtain good matching and gain in a frequency interval of 4 to 18 GHz will be d...

An adaptive antenna array based propagation delay CDMA communication systems

This paper discusses the propagation delay estimation problem for DS-CDM4 based on an adaptive antenna array whzch can suppress interfering signals. The tap weights of the adaptzve beamformer are controlled by two adaptive algorithms such as direct matrzx inver.won (DM7) and linearly constrained minimum variance (LCW). The large sample maximum likelihood (ZSML) estimator is applied to the beamf...

Adaptive Array Antenna Processing

This paper, specifically written for GradCon ’99, presents an overview of the field of adaptive arrayprocessing. Beginning with a brief review of array synthesis theory, the concept of an adaptive array is introducedand defined. The broad field of adaptive array applications can be divided into two categories: adaptive signalprocessing for multiple access communication systems, and ...

A complex adaptive delay filter

In this paper we propose an adaptive delay filter with complex coefficients for identifying an unknown system with complex sparse impulse response. The delay taps can not be determined by the conventional real adaptive delay filter, which evaluates the mean squared error with one constant gain in the system with complex coefficients. In the proposed method, a modified evaluation function, which...
