Optimum Design of a 4x4 Planar Butler Matrix Array for WLAN Application

In recent years, high-speed wireless communication is in vogue. In wireless communication systems, multipath fading, delay and interferenc occurres by reflection or diffraction. In a high-speed wireless communication, it becomes a necessary to separate desired signal from delay or interference signal. Thus to overcome these problems Smart antenna systems have been developed. Basically there are...

A New Design of Log-Periodic Dipole Array (LPDA) Antenna

This paper presents a new approach for design of the log-periodic dipole array antenna (LPDA) based on using of different design parameters in the LPDA elements to control the antenna behavior. In the proposed procedure, the design parameters can control the value of forward gain over the operating frequency range, and also adjust the gain flatness. Furthermore, this design procedure can decrea...

Circularly Polarized Circular Slot Antenna Array Using Sequentially Rotated Feed Network

This paper presents the design, simulation, and measurement of two low-cost broadband circularly polarized (CP) printed antennas: a single element and an array at C band. The proposed single element antenna is excited by an L-shaped strip with a tapered end, located along the circular-slot diagonal line in the back plane. From the array experimental results, the 3 dB axial ratio bandwidth can r...
