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...
15 صفحه اولMicrostrip 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 ...
متن کاملCompact Dual-Frequency Microstrip Antenna Array with Increased Isolation Using Neutralization Lines
An effective technique utilizing neutralization lines to increase the isolation of a compact two-element dual-frequency microstrip antenna array is proposed in this paper. Two neutralization lines connect the two elements at the edge of each radiating patch. The positions and lengths of the two neutralization lines are studied to get the best performance of element isolation. A prototype of the...
متن کاملMicrostrip Coupler with High Isolation
A method to improve the isolation of the microstrip coupler is presented. The pattern of the coupler is modified for phase velocity compensation which results in high isolation. Using this procedure, a 15 dB coupler is designed and fabricated at 0.9 GHz. A high isolation of 63.3 dB is measured. The validity of the design concept is verified by simulations and measurements.
متن کاملDual 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...
