Uma nova antena polarizada circularmente com slot quadrado para características de banda larga é proposta neste artigo. Os componentes horizontais e verticais da sonda em forma de L, elemento chave para gerar a polarização circular, estão separados na estrutura, ao contrário do conceito de sondas unidas. Outra novidade, a colocação de stubs no slot, que são fixados ao plano de terra, é proposta para melhorar as características de relação axial (AR) da antena em cerca de 10%. Colocando um refletor a uma distância de λ0/4 da antena para obter padrões unidirecionais é eficaz quando nenhum stub é colocado no slot. A antena atinge uma largura de banda de perda de retorno < 10 dB de 47.5% (2.76-4.48 GHz) e largura de banda de razão axial (AR) < 3 dB de 42.47% (2.67-4.11 GHz) em medição. Estudos paramétricos sobre parâmetros-chave e resultados medidos também são apresentados.

Abstract: A novel circularly polarized antenna with square slot for broadband characteristics is proposed in this paper. The horizontal and vertical components of the L-shaped probe, which is a key element to generate circular polarization, are separated in the structure, contrary to the concept of joined probes. Another novelty, placing stubs in the slot, which are attached to the ground plane, is proposed to improve the axial ratio (AR) characteristics of the antenna by around 10%. Placing a reflector at a distance of λ0/4 from the antenna to obtain unidirectional patterns is effective when no stubs are placed in the slot. The antenna attains a < 10 dB return loss bandwidth of 47.5% (2.76-4.48 GHz) and < 3 dB axial ratio (AR) bandwidth of 42.47% (2.67-4.11 GHz) in measurement. Parametric studies on key parameters and measured results are also presented.
