A microfluidically frequency-reconfigurable microstrip patch antenna and an array are proposed in this paper. The reconfiguration performance is realized to be frequency-hopping by inserting polypropylene tubes. which act as microfluidic controllers selectively filled with deionized (DI) water between the patch and ground plane. It is a low-cost and environment-friendly choice for fre... https://danddcollectiblers.shop/product-category/baking-set/
