Aqui, uma nova antena de matriz integrada ativa auto-oscilante (AIAA) é proposta para aplicações de banda X de comutação de feixe. O AIAA proposto compreende quatro elementos de antena microstrip polarizados linearmente, um oscilador Gunn, dois magic-Ts planares e dois interruptores unipolares de lançamento único (SPST). A abordagem de combinação de sinal em / anti-fase empregando magic-Ts planares é adotada para atingir padrões de radiação bidirecionais no φ = 90° avião com estrutura simples. A antena proposta pode mudar seu feixe usando os switches SPST. A antena é analisada através de simulações, e um protótipo da antena é fabricado e testado para validar o conceito. O conceito proposto é considerado viável; o protótipo tem uma potência isotrópica irradiada efetiva de +15.98dBm, nível de potência irradiada de +4.28dBm e supressão de polarização cruzada melhor que 15dB. Os padrões de radiação medidos estão de acordo com os resultados da simulação.

Abstract: Herein, a novel self-oscillating active integrated array antenna (AIAA) is proposed for beam switching X-band applications. The proposed AIAA comprises four linearly polarized microstrip antenna elements, a Gunn oscillator, two planar magic-Ts, and two single-pole single-throw (SPST) switches. The in/anti-phase signal combination approach employing planar magic-Ts is adopted to attain bidirectional radiation patterns in the φ =90° plane with a simple structure. The proposed antenna can switch its beam using the SPST switches. The antenna is analyzed through simulations, and a prototype of the antenna is fabricated and tested to validate the concept. The proposed concept is found to be feasible; the prototype has an effective isotropic radiated power of +15.98dBm, radiated power level of +4.28dBm, and cross-polarization suppression of better than 15dB. The measured radiation patterns are in good agreement with the simulation results.
