Abstract

This paper presents a bandwidth enhancing technique using a modified ground plane with diagonal edges, L-shaped slot and parasitic patches with main patch for the design of compact antennas. The proposed low-cost, compact-size rectangular patch antenna on 4. 7?cm × 3. 6?cm printed circuit board (FR-4) is designed and validated through simulations and experiments. Results show that the ground plane with L-shaped slot in presence of the diagonal cuts at the top corners and the rectangular parasitic patches can increase the bandwidth. Return losses of ?23. 6 dB and ?29. 7?dB for the first and second resonant frequencies, respectively, can be achieved when the depth of the diagonal cut is 3 mm, the dimension of each rectangular parasitic patch is 10 mm×3. 5?mm, and the L-shaped slot size is 7. 5 mm ×2. 5mm, providing a 41. 27% wider bandwidth than Federal Communication Commission's(FCC) standard.
