Sequentially Rotated Array Microstrip Antenna

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...

an infinite planar array of rectangular microstrip patch antenna analysis

the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

Dual Linearly Polarized Microstrip Array Antenna

Recently, Multiple Input Multiple Output (MIMO) has become popular research topic among researchers for development of a new wireless communications technology. The system capacity can be increase with deployment of MIMO technique in the communications system. Thus, the used of high frequency bandwidth can be avoid since this method required high cost implementation. High transmitted power also...

Microstrip Antenna Array with I-Shaped DGS

This paper proposed a microstrip antenna array with DGS (Defective Ground Structure). The structure in this work is 2*1 microstrip patch array antenna using substrate with h= 0.762 mm and εr = 3.2. Two triangular-shaped patches are located on opposite side of PCB and spaced 14mm apart by a small ground portion. The proposed DGS of I-shape is placed in the ground plane. It does provide a method ...
