技術說明

本發明係一種差分饋電TM05模貼片陣列天線，包括天線層、複數個波導層、複數個耦合層及接地層，其中天線層包括第一介質板及設在第一介質板的M × N陣列排列的微帶TM05模貼片天線，各微帶TM05模貼片天線在E平面方向之陣間距可大於1個波長(λ)，且各微帶TM05模貼片天線的反向電流位置分別設有複數個開槽，各波導層與各耦合層係設在天線層與接地層之間，且依序為一個波導層與一個耦合層交錯疊合，而形成差分饋電模組，差分饋電模組是利用振幅相同且相位相反的兩路訊號同時饋電至同一微帶TM05模貼片天線上，完成高增益、低旁瓣及低交叉極化天線設計。 This invention relates to a differentially-fed TM05-mode patch array antenna, which includes an antenna layer, a plurality of waveguide layers, a plurality of coupling layers and a ground layer, wherein the antenna layer includes a first dielectric substrate and M × N disposed on the first dielectric substrate microstrip TM05-mode patch antennas arranged in an array, the array spacing of each microstrip TM05-mode patch antenna in the E-plane direction can be greater than 1 wavelength (λ), and the reverse current positions of each microstrip TM05-mode patch antenna has a plurality of slots, each waveguide layer and each coupling layer are arranged between the antenna layer and the ground layer, and a waveguide layer and a coupling layer are alternately overlapped in sequence to form a differentially-fed module. The differentially-fed module uses two signals with the same amplitude and opposite phases to feed the same microstrip TM05 patch antenna at the same time to complete the design of high gain, low sidelobe, and low cross-polarization antenna.
