This contribution presents the system design procedure and performance of an array fed reflector antenna. Combining the inherent benefits of a reflector antenna—high gain, low-cost, and simplicity—with the agility provided by a scannable active array feed, enables a new range of applications, for instance in commercial mobile antenna terminals. The whole arrangement features a restricted field of...
This paper discusses antenna array integration concepts for combined receiver (Rx) and transmitter (Tx) terminals that can be used for ground based Ka-band satellite communications (SatCom). The combination of Rx and Tx enables very compact array architectures, which eases integration on mobile platforms. The associated challenges are discussed in the SatCom context and a comprehensive analysis of...
In this study a sparse MIMO system with difference co-array processing is presented. It consists of two dense transmitter arrays in split configuration and a symmetrical hybrid receiver array. A combination of a periodically thinned array and two non-uniform sub-arrays is proposed to synthesize the receiver structure with low optimization effort. High angular resolution is achieved in the MUSIC spectrum...
In this contribution a dual-band, dual-polarized microstrip antenna is presented. The antenna is designed for ground based Ka-band satellite communications. It relies on a standard multilayer printed circuit board technology to minimize production cost. The antenna size is smaller than half the freespace wavelength at 30GHz enabling its utilization as an array element. The dual-frequency characteristics...
