ABSTRACT

This paper introduces the design of rectangular multi-band H-shaped microstrip
antenna with rectangular slot (RMSA). A special H-structure with constant substrate
thickness was simulated for the proposed antenna, and the effects of different stub sizes on
rectangular patch antenna performance were investigated. A balanced patch antenna has
been designed and analyzed at frequencies of (1 to 6.5 GHz). COMSOL Multiphysics
program was used for the simulation. The resonant frequencies and radiation characteristics
were analysed. Different frequencies used for Radio Frequency Identification RFID,
Worldwide Interoperability for Microwave Access (Wimax) and computer network
applications were tackled.
