Developing a space system is a challenge which includes risk that increases with the lack of practical experience especially for a new player in space industry. A concurrent design facility (CDF) with especially tailored work stations can lower the risk of lack of experience through increasing the team interaction as additive experience and decrease over design budgets generated by designers as a...
This paper introduces an UWB antenna in coplanar waveguide configuration. Two design approaches were employed to trade off between the good matching properties and stable radiation pattern so as to obtain optimum performance over the entire bandwidth of interest. Detailed design approach validated by full wave simulation and experimental results is introduced to confirm the performance of reported...
Reflectarray composed of 23 × 23 elements covering an area of 276 × 276 cm2 is constructed. The unit cell consists of rectangular DRA, a slot in the ground plane, a dielectric layer, and a conducting ground plane. The full phase of 360 degree of the array elements can be obtained by using two slot-ground plane sizes. The reflectarray is centred fed by linearly polarized pyramidal horn antenna. Full-wave...
Slot-loading rectangular DRA elements reflectarray antenna was designed for linear polarization at X-band. The antenna was center fed by a linear polarized pyramidal horn. The array size is 23 x 23 elements reflectarray. The finite integration technique was used to compute the radiation patterns and the gain of the antenna. The method was verified by comparing the results with transmission line method...
An array of aperture-coupled dielectric resonator (DR) reflectarray is used to realize a reflectarray antenna in X-band. The reflectarray composed of 23 × 23 elements and covering an area of 27.6 cm × 27.6 cm. The unit cell in reflectarray antenna consists of rectangular DRA, a slot in the ground plane, upper substrate, sub-loaded transmission line of variable length, lower substrate, and conducting...
