Modified Compact High Gain Multiple Patch Slotted Microstrip Antenna for Multiband Wireless Applications

A modified approach for the design of a compact multi-element patch antenna which operates in pentaband is proposed. The antenna comprises of a main patch with subpatches containing resonating slots. The main patch is fed with a 50Ω microstrip line. The antenna operates with multiple operational frequencies covering the bands from 1.9GHz to 9.5GHz with good impedance matching. The design is verified using simulation software ANSOFT HFSS and tested using the laboratory experimental approach which resembles the simulated output with an omnidirectional radiation characteristics.The multipatch antenna achieved a Peak Gain of 14.47 dB at 8.38 GHz and stays above 2.42 dB through the entire operating band. The frequency of operation is suitable for wireless devices supporting multiple standards including Universal Mobile telecommunication System (UMTS, 1920-2170 MHz), Wireless Local Area Network (WLAN, 2400-2483.5 MHz) and low band Worldwide Interoperability for Microwave Access (WIMAX, 2.5 to 2.8 GHz).
