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 اولElectronically Steerable Parasitic Array Radiator Antenna − Principle , Control Theory and Its Applications −
Principle, control theory, and application of the ESPAR (Electrically Steerable Parasitic Array Radiator) antenna are introduced. A typical ESPAR antenna consists of monopole or dipole elements, one of which is the radiator (fed element) and the others are the parasitic radiators with variable reactance devices loaded on them. It can provide a lower-cost solution as an adaptive array antenna or...
متن کاملPerformance of Adaptive Beamforming with Multiport Parasitic Array Radiator Antenna
Modern wireless communications systems require improvement in capacity and data transmission speed. Adaptive array antennas separate spatially a desired wave from interference waves by controlling their radiation or beam pattern directivity. A digital beamforming (DBF) array performs adaptive beamforming by digital signal processing. However, the circuit scale, number of RF channels and power c...
متن کاملDesign of a Dualband Omnidirectional Planar Microstrip Antenna Array
This paper proposes and designs a new method of dualband omnidirectional planar microstrip antenna array. A cascade of transposed microstrip lines have been adapted to produce effective antenna structures that radiate omnidirectionally, with high efficiency, low reflection, and useful radiation patterns. In this paper, the antenna structure has been found to have low-pass characteristics due to...
متن کاملDesign Investigation of Microstrip Patch and Half-Mode Substrate Integrated Waveguide Cavity Hybrid Antenna Arrays
In this paper two linear arrays including a linear 1×4 and a planar 2×2 of microstrip patch and half-mode substrate integrated waveguide (SIW) cavity hybrid antenna are introduced and investigated. These are simply implemented using low cost single layer printed circuit board (PCB) process. The array element consists of a rectangular microstrip patch with appropriate dimensions in the vicinity ...
