“…The DAG is determined in terms of SNR enhancement at a specific outage probability (OP) 1 u (DAG-OP) and in terms of average SNR reduction for achieving a specific average bit error rate (BER) 2 u (DAG-BER) [6]. In order to find both DAGs, the PDF and CDF of received SNR are needed.…”

“…The stochastic electromagnetic simulation methods are Monte Carlo-based and apply when no mathematical expressions for the CDF of received SNR are available. In such cases, simulation schemes for modeling the antenna patterns and incoming plane waves are the only option [1]. Alternative non-analytical methods for performance evaluation have employed the use of reverberation chambers emulating rich isotropic multipath environments [4], [5].…”

“…(13)). The latter was recently introduced in [1] as a condensed parameter for accurate modeling of the radiation fields of any MPA type by rigorously applying the reciprocity principle in such systems and generalizing the effective length concept of single antennas. Thus, the proposed formula physically incorporates the impact of propagation environment, termination conditions and MPA radiation characteristics on diversity performance evaluation.…”

Abstract-In this paper, we present a new electromagnetic methodology that determines the covariance matrix of compact multi-port antenna (MPA) systems at the early design stage. Further insight to this field is provided, as contrary to existing methodologies, it rigorously relies on the reciprocity principle of MPA systems. Thus, the impact of propagation environment, termination conditions and MPA radiation characteristics as independent factors affecting performance is physically incorporated. Provided the availability of mathematical expressions for the cumulative distribution function (CDF) and probability density function (PDF) of received signal-to-noise ratio (SNR), performance can be then analytically studied via the diversity antenna gain (DAG) in terms of a) SNR enhancement at a specific outage probability (OP) level (that is DAG-OP) and b) average SNR reduction for achieving a specific average bit error rate (BER) (that is DAG-BER). Illustrative examples with performance evaluation of compact MPA systems are presented. The adopted diversity technique is the transmit antenna selection/maximal ratio combining (TAS/MRC), which for the first time is analytically studied employing realistic MPA systems. Comparisons with existing published results further demonstrate the validity and usefulness of the proposed methodology.Index Terms-Antenna diversity, Covariance matrix methodology, Diversity antenna gain, Multi-port antenna systems.

In this letter, the performance of actual multielement antenna (MEA) systems under the transmit antenna selection/maximal ratio combining (TAS/MRC) technique is evaluated. An alternative version of an efficient, recently developed, stochastic electromagnetic methodology is employed to investigate the TAS/MRC performance of five MEA systems operating in the 5.2-GHz ISM band. The MEA systems are comprised two up to six printed antennas, and their performance is evaluated through the diversity gain (DG) at 1% outage probability level. Interestingly, DG degradation is revealed when the number of receiving antennas is six. Index Terms-Antenna diversity, maximal ratio combining (MRC), outage probability, transmit antenna selection (TAS).
