An experimental investigation of a pyramidal microstrip antenna array fed by coplanar waveguides is presented. The use of a very thin substrate for coplanar lines allows not only a planar design but also simplifies realisation by the bending lines. The measured radiation pattern of this array is similar to that obtained when a classical probe...

A theoretical analysis of microstrip antennas printed on a conical surface operating in the TM01 model is described. The cavity mode with magnetic or electric walls is used to calculate the resonant frequency and the input impedance. The radiated far fields are obtained by using the dyadic Green's function formulation. Experimental data fit the...

Coplanar waveguides nowadays are successfully used to feed printed antennas. This technique is very interesting for antenna arrays. However, the complete system involves the association of several microwave functions, essentially power divisions and phase shifts, which are easier to implement in microstrip technology than in CPW technology. In...

An antenna array synthesis method based on the simulated annealing algorithm is presented. The synthesis is carried out on the total electrical far field in magnitude and polarization. This method uses the flexibility of the simulated annealing technique to optimize both complex feed currents and angular arrangements of the elements.
