Abstract :
In this letter, the use of artificial magnetic conductor (AMC) to load a monopole antenna has been investigated. It is known that the current reversal, which occurs at frequencies much beyond the antenna natural frequency, disturbs the omnidirectional radiation pattern of the monopole antenna. The current distribution of the monopole antenna can be improved to a large extent by using perfect magnetic conductor (PMC) loading. To this aim, the capacitively loaded loops (CLLs) are used to realize PMC behavior.
