Design of Multiband Monopole Antenna for Wireless Applications

摘要

A highly compact microstrip-fed monopole antenna for Wireless Local Area Network (WLAN) and satellite communication is proposed. The proposed antenna design has different geometry manipulation to achieve multi band performance with reduced size than existing antenna. The antenna consists of compact rectangular patch as a radiator that is fed directly by a 50 Ω microstrip line. The rectangular patch consists of L-and U-shaped slots and ground plane. The proposed antenna consists of very small radiating patch when compared to existing double- and triple-band monopole antennas. The radiator is highly compact with the size of 12.5 × 10 × 1.6 mm~3. The simulation results show that the designed antenna is capable of operating over 3.5 GHz, 4-4.9 GHz and 5-8 GHz frequency bands while rejecting frequency ranges between these three bands. The design has been simulated using Advanced Design System (ADS) 2016.
