Symmetrical series-fed dual-polarised microstrip antenna lattice with odd number of radiating elements

摘要

A concept of symmetrical microstrip antenna lattice having an odd number of radiating elements has been proposed. In the presented antenna array, all radiating elements are connected in series along both and axes, which allows for generation of dual polarisation and for reduction of dissipation losses in the feeding network. The proposed approach extends the idea of the previously developed antenna lattice, in which an even number of radiating elements has been considered. This study presents the design procedure for the proposed concept, which is confirmed by simulations and measurements of the developed 5 × 5 antenna lattice operating at 5.4 GHz.
