Some Aspects on Design, Simulation, Fabrication, and Analysis of a Multi Frequency Micro-Strip Antenna

Abstract

In this work we discussed in details about the fabrication of a rectangular micro-strip antenna with an inclined slit of 100μm width for multi band operation. A simple rectangular micro-strip antenna is first designed for its operation in the S-band at 2.43 GHz. Then, we introduced a 100μm inclined slit on the antenna connecting the two radiating edges which results in multi band operation. Simulations are performed to study the effect due to the slit at different locations of the antenna with different angle of inclination. Prominent result of multi band operation in L and S-bands are observed with the slit introduced on it. Considering the simulation results, antenna prototypes with the best configuration are fabricated which show best results for multi band operations. Various parameters of the fabricated antenna are measured experimentally and are compared with the simulation results. The proposed method is simple and it can be fabricated easily to achieve best results.
