Mobile communications experiments on dual-band triangular-patch array antenna using a pseudo satellite

A simple satellite-tracking array antenna for mobile satellite communications aimed at ETS-VIII applications has been discussed. The proposed antenna is constituted of triangular patches sequentially rotated by 120/spl deg/. By successively turning off any one of the patches, it is shown that three beams are created in the conical-cut plane for transmission and reception. Furthermore, the gain can reach more than 5 dBic on the whole azimuth range for an elevation El = 48/spl deg/ in Tokyo. Mobile satellite experiments using the developed antenna and a pseudo satellite are performed. According to the results, the received power is in agreement with the calculations.
