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...
متن کاملUltra-Wideband Array Antenna Utilizing Novel Scanning System with Tapped Delay Lines for Short Range Radar
A UWB impulse array antenna (IAA) utilizing a novel electrical scanning system with tapped delay lines is proposed and its usefulness is experimentally verified. The experimental antenna is composed of impulse generators installed in each antenna element and tapped delay lines used for creating transmitting trigger signals, which is a simple circuit configuration. It is shown that the output ph...

متن کاملTDL-based Wideband Beamforming for Radio Sources Close to the Array Endfire
Uniform linear array (ULA)-based tapped-delay line (TDL) structure has good performance metrics when the signal sources are located at the middle angles. It offers poor performance when the signal sources are close to the array endfire. In this paper, a new approach is proposed which offers higher performance and desired beamforming on TDL structure when the wideband uncorrelated radio sources ...
متن کاملBeamforming Using Tapped Delay Line Filters for Broadband Cdma Systems
We investigate the performance of uncoded uplink transmissions in a broadband code division multiple access (CDMA) system using a tapped delay line (TDL) antenna array. First, the weights of a TDL antenna array are derived for broadband CDMA. Using these weights, we perform simulations to demonstration how TDL antenna arrays can help reduce multi-access interference (MAI), allow the use of spre...
