Design and analysis of slotted sectoral waveguide array antennas embedded in cylindrically stratified media

Kalfa, Mert; Ertürk Vakur B. (IEEE, 2014-07)

Slotted waveguide antennas are being widely used in military and commercial applications for many decades. Low cross-polarization, high power capacity, ease of fabrication in microwave bands, and the ability to form arrays ...
Phase-only beam synthesis by iterative semidefinite relaxations with rank refinement

Alp, Yaşar Kemal; Arıkan, Orhan; Bayri, A. (IEEE, 2013)

In phased array antennas, by varying the complex element weights beam patterns with desired shapes can be synthesized and/or steered to desired directions. These complex weights can be implemented by using amplitude ...
