Design and Optimization of Slotted Micro-Machined Patch Antenna Using Composite Substrate

摘要

A slotted L-shaped micro-machined patch antenna on composite substrate has been proposed in this article. The slotted patch has been designed on the composite substrate with overall height of 1.675 mm and effective dielectric constant of 3.23. The desired frequency and bandwidth has been achieved by the parametric optimization using Ant Lion optimization technique. The design resonates at 8.1 GHz and 13.5 GHz with the gain of 6 dBi. The simulated and measured results are quite promising. The obtained resonating characteristics of the proposed design are used in the earth exploration satellite services defined by ITU.
