Experimental investigation of the novel feed-in scheme for LO based on the near-field coupling

Abstract

A novel feeding scheme of local oscillator feeding based on the near-field coupling was proposed in Luan et al. (2003). The coupling effectiveness between two single feeding elements as well as the microstrip arrays was investigated, showing that a good transportation of the power may be realized through appropriate design. This paper presents the experimental results for both transmitting efficiency and assembling tolerance. Very close agreement has been obtained between simulated and measured performance of the proposed feeding scheme.
