Switching rate plays an important role for system engineers in the design of selection diversity receivers. Switching antennas is similar to applying a step function to the receiver circuits, which causes transients in the receiver filters. These deleterious transients will corrupt channel estimation as well as creating “dead” time in the receiver filters. Recent work has studied the switching rates...
In this paper, we present a time-varying matching design for electrically small antennas in pulse-based systems. The proposed technique is applied to small loop antennas in the receiving mode. Simulated results show that substantial improvement in the overall antenna efficiency can be achieved without dispersion that is one of the major limitations of a conventional matching network of equivalent...
