This paper proposed a simple design of integrated system for wireless backhaul network that can work as a wireless bridge and access point. This system has an antenna which is designed to work with frequency range 2.4-2.4835GHz IEEE802.11g standard and intended for point to multi point link. Another antenna designed on frequency range 5.725-5.825GHz unlicensed band IEEE802.11a standard for point to point link. Therefore, two antennas on different frequencies and polarizations has been developed and finally incorporated with a router board with two radios. First antenna is the Radial Waveguide Slot Array (RWSA) which is an uni-omni directional antenna performs as wireless access point and supports 2.4 GHz clients. The initial element design was optimized in the structure based on Zeland Fidelity, FDTD (Finite-Difference Time-Domain) with Full-3D EM Simulation for the radiation pattern as well as return loss. Second antenna used is Radial Line Slot Array Antenna (RLSA), which is directional antenna and used for main internet source. Return loss, gain and radiation pattern simulated by software which is developed on Borland C++ 5.0. Tests were setup in different environments, in the lab and outdoors and practical measurements has been taken to validate the simulation results and performance. The proposed design can find its applications in wireless communication systems, especially where cost-effective high-speed wireless Internet access service is required.
