This study concern reconfigurable antenna and their feeding circuit. Directivity and polarisation agility is obtained using different active components as PIN diodes and varactors which directly reported on the feeding circuit using MIC (microwave integrated circuit). A novel architecture of quasi-lumped coupler based on varactor is proposed,...

Circular polarization is an essential feature for small antennas designed to connect with satellite navigation systems. Here, a Q-factor optimization problem constrained with a circular polarization radiation requirement is formulated and solved. The constrained problem is shown to be solvable as fast as calculating the Q-factor bound without...
