The scattering from an object can be reduced by using active microstrip antenna elements to cancel the scattering from the object. Sensors are placed on the object to sample the local field at the surface of the object. This information is then used to adjust the radiation from the antennas in order to cancel the scattering from the object.
A circularly-polarized (CP) microstrip antenna with both large impedance bandwidth and large circular polarization bandwidth is proposed. The antenna consists of two dual-mode nearly-square sub-patches that are each optimized to achieve maximum bandwidth. The two sub-patches are then used to construct an overall CP antenna.
Transparent broadband circularly-polarized (CP) microstrip antennas on a quartz or Lexan substrate are developed for CubeSats. Two designs for the 2.4 GHz ISM band are presented. Both designs use a wire mesh for the antenna and ground plane.
A novel method of analysis for a linear series-fed microstrip antenna array is developed, which is based on a set of canonical coefficients defined for the elements of the array. This method accounts for the mutual coupling between the elements, and allows for a design that has an arbitrary amplitude and phase of the radiating patch currents. This method has the simplicity of a CAD approach while...
