Antena jalur mikro dengan satah tanah bersirat sesuai untuk unsur sinaran antena tatasusunan berfasa satelit yang besar. Walaupun mereka mempunyai beberapa kelebihan mekanikal seperti kemungkinan pengurangan berat antena, ia juga menyebabkan masalah elektrik seperti anjakan frekuensi resonan dan penurunan nisbah F/B. Tujuan pertama kertas ini ialah pemahaman analitikal anjakan frekuensi resonan, yang mana dua kaedah gangguan dicadangkan. Satu mempunyai ungkapan bentuk tertutup yang menyediakan beberapa data reka bentuk yang berguna. Yang lain adalah untuk menyelesaikan persamaan kamiran dengan menggunakan keberkalaan satah tanah bersirat, yang memberikan hasil yang lebih tepat. Tujuan kedua kertas ini adalah untuk menyiasat sinaran ke belakang dari satah tanah bersirat secara analitikal, yang mana kami memperoleh kaedah analisis daripada hasil pengiraan anjakan frekuensi resonan. Kaedah yang dicadangkan disahkan dengan kaedah yang diukur.

Abstract: Microstrip antennas with meshed ground planes are suitable for radiation elements of large satellite phased array antennas. Although they have some mechanical advantages such as the possibility of antenna weight reduction, they also cause electrical problems such as the resonant frequency shift and F/B ratio degradation. The first purpose of this paper is the analytical understanding of the resonant frequency shift, for which two perturbational methods are proposed. One has a closed form expression that provides some useful design data. The other is to solve the integral equations by using the periodicity of the meshed ground plane, which gives more accurate results. The second purpose of this paper is to investigate the backward radiation from the meshed ground plane analytically, for which we derive an analysis method from the calculated results of the resonant frequency shift. The proposed methods are verified with the measured ones.
