Abstract
In this paper, MEMs-based smart patch antennas which can be used for biomedical applications were investigated. An attention over the main constraints in designing efficient antennas for biomedical devices was made and the analysis is presented, in addition with some of the main issues in their categorization. The foremost constraint which was encountered during simulation was the miniaturization problem. As the size of the antenna is reduced different parameters of the antenna such as directivity, gain, antenna efficiency show degradation in values. The patch antenna is a trendy antenna which can be used in various sophisticated applications due to its small size, robust nature, and low power handling capacity which is the prerequisite in our study. The antenna which has been developed basically consists of a patch antenna along with a meta-material-based rectangular slot over the patch. Bulk micromachining technique is used to etch out certain portions of the silicon substrate and Rogers RT-duroid substrate is intentionally been added within the micro-machined portion. MEMs-based switches have been added in our design in order to make the antenna reconfigurable in nature. The results obtained after simulation is astonishing with considerable increase in bandwidth, directivity, and gain which make the antenna viable for the required purpose despite of considerable reduction in size of the antenna.
