Abstract

A K-band patch antenna with reconfigurable frequency and polarization properties is proposed. It can be operated in two distinct frequency bands around 20GHz and can be switched between left and right hand circular polarization. The operating mode is changed by means of pin diodes. The geometry and the radiation behavior are optimized for array applications. The antenna relies on a standard printed circuit board technology. It is therefore well suited for ground segment applications in future Ka-Band satellite communications. The paper presents the antenna design, the optimization, and the verification through simulation and measurement.
