Abstract
The research in wireless communication has spurred the development of extra ordinary range
of antennas, each with its own advantage and limitations. In today’s modern communication
industry, antennas are the most important components required to create a communication link.
Microstrip antennas are an urgent need for aerospace and mobile applications because of their low
profile, light weight, flexibility to efficiently combine the capabilities of multiple antennas and
low power handling capacity.
Conventional Microstrip patch antennas has some drawbacks of low efficiency, narrow
bandwidth of the central frequency, its bandwidth is limited to a few percent which is not
enough for most of the wireless communication systems nowadays. The project provides a
detailed study of the design of coaxial-fed Rectangular Microstrip Patch Antenna to facilitate
dual polarized, dual band operation. The design parameters of the antenna have been calculated
using the transmission line model and the cavity model. For the simulation process HFSS (High
Frequency Structural Simulator) which is electromagnetic software based on finite element
method (FEM) has been used. The effect of antenna dimensions and substrate parameters on the
performance of antenna have been discussed.
The antenna has been designed with embedded spur lines and integrated reactive loading for
dual band operation with better impedance matching. The designed antenna can be operated at
two frequency band with centre frequencies 2.44 GHz (Bluetooth) and 5.5 GHz (Wi-Fi). So the
dual band and dual frequency operation has successfully incorporated into a single patch.
