This paper presents a four-stage algorithm for the realization of multi-input/multi-output (MIMO) switched linear systems (SLSs) from Markov parameters. In first stage, time-varying (LTV) that is topologically equivalent to true SLS derived parameters assuming discrete states have common MacMillan degree and mild condition on their dwell times holds. second stationary point set Hankel matrix wi...

A <span>good antenna design has played an essential role in the of wireless communication systems, international companies are looking for best that suits their products terms size, bandwidth, gain, cost, and performance. In this paper, three models designed fifth-generation (5G) communications, first model is a single antenna, second two-ports multi-input multi-output (MIMO) third four-p...
