Design of Broad-Beam Microstrip Reflectarray
The reflectarray’s elements arrangement for generating an arbitrary phase distribution in the antenna aperture and thus a wide beamwidth of the far field pattern is presented. The desired phase delay of reflectarray elements, which duplicated the same radiating aperture as backscatters, is determined on the construction of the curvature of a shaped backscatter surface with the help of Snell's l...
متن کاملPerformance Improvement in the Design of Broad-Beam Microstrip Reflectarray
This is a theoretical and experimental study of microstrip reflectarray useable in wireless local area networks (WLAN). The effectiveness of reducing the unit cell size of microstrip reflectarray which is duplicated the same radiating aperture as quadratic backscatter was investigated. A reflectarray with variable element sizes and reduced grid spacing have been designed at 10 GHz. For a given ...
متن کاملDesign and Performance Improvement of Broad-Beam Microstrip Reflectarray
of reducing the unit cell size of microstrip reflectarray which is duplicated the same radiating aperture as quadratic backscatter. A reflectarrays with variable element sizes and reduced grid spacing have been designed at 10 GHz. For a given number of elements, it is shown that increased gain can be attainted for reduced unit cell size with no significant change in array size.
متن کاملRing Shaped Compact Microstrip Reflectarray Antenna
Regularly shaped compact microstrip antennas have a small size but their gain is insufficient for most applications. Therefore, a ring-shaped compact microstrip reflectarray with microstrip antenna feed has been proposed. Different configurations, namely, 1 × 3, 3 × 1, plus-shaped and 3 × 3 have been analyzed. The 3 × 3 configuration yields an optimum gain of 10. 8 dBi and a narrow beamwidth of...
متن کاملBandwidth Considerations for a Microstrip Reflectarray
The paper describes a theoretical investigation into a limited bandwidth operation of a microstrip reflectarray. Two main factors limiting the bandwidth are considered. One is related to the requirement of phase compensation to convert a spherical wavefront launched by a feed into a planar wavefront. The other one is linked to the limited phasing range of microstrip antenna elements. The two fa...
