Implementation and comparison of existing ICCLMA and proposed minuscule ICCLMA using CST

Antenna size reduction is one of the major problems in wireless communication devices. For this process many design topologies have been proposed. Some of them are capacitive loaded monopole antenna, (PIFA) planar inverted-F antenna, low profile multi element miniaturized monopole antenna (LMMMA) and Inductively Coupled Capacitively Loaded Monopole antenna (ICCLMA). The existing antenna techniques reduce the size but with leads to lower gain. Then the ICCLMA was designed as 15×55mm with gain as 9.9 dB. Recently a new antenna topology called proposed minuscule ICCLMA, which greatly reduce the antenna size to 3.393×0.0474mm but provides a higher gain of 45.24B.This paper includes the literature survey of existing small size antennas, implementation of ICCLMA and proposed minuscule ICCLMA using CST (Computer Simulation Technology). It also includes the comparison of ICCLMA and the minuscule ICCLMA.
