Size reduction of microstrip antenna with CRLH-TL metamaterial and partial ground plane techniques

摘要

The development of wireless technology today needs components and devices to become smaller and compact. Antenna is one of the important component in wireless communication device, therefore antenna size reduction is also indispensable. There are various techniques to reduce the antenna size. Metamaterial is one technique that can be used for antenna size reduction [1]. The Mushroom Structured Composite Right/Left Handed transmission line (CRLH-TL) metamaterial is chosen. The choice is due to its advantages, which are: antennas size reduction, bandwidth enhancement[2], and gain improvement[3].
