Performance analysis of an LMS adaptive array with inverted-F elements on a rectangular conducting body

The authors present a theoretical performance analysis of a two-element LMS adaptive array antenna in the mobile communication environment when the inverted-F antenna (IFA) is used as the array elements. The array SINR (signal to interference-plus-noise ratio) performance is analyzed three-dimensionally when the array elements are placed on a finite rectangular conducting body which may be a model of a vehicle or a tower. The inter-element coupling and diffraction effect of the conducting body are taken into account in the calculation. The IFA array performance is compared with a similar array with quarter-wave monopole elements. A factor called SINR pattern angle ratio (PAR) is used to discuss the quantitative evaluation of the system performance.<
