Abstract: This paper presented a Triple Frequency passive array stacked patch antenna, which work on the L-band frequencies of 1.25 GHz, 1.46 GHz and 1.65 GHz. The array contained 16 rectangular stacked patch antenna elements and these 4×4array were fed by independent coaxial method. This design reduced the effects of the complex feeding network on antenna performance and the distance between each antenna element was only half of free space wavelength, so the size of whole array was reduced significantly. This antenna can also be combined into a bigger array with more elements, then make the miniaturization of the array more obvious.

Keywords: Miniaturization, Multi Frequency, Passive Array, Stacked Patch
