Antennas

Tokyo Inst. of Tech. (CUTE –1) Three Antennas One 500 mm (or /4) antenna for MHz. Two 170 mm (or /4) antennas for MHz and MHz. All three antennas are < 4 mm wide.

Tokyo University (XI–III) Two Antennas One monopole antenna for MHz. One dipole antenna for MHz (telemetry) MHz (beacon). The image to the right is the radiation pattern of the transmitter’s /2 dipole antenna.

StenSat (CubeSat) Center-fed dipole antenna made out of piano wire

StenSat (Pico Satellite) Two Dipole Antennas One 2 Meter dipole antenna for MHz One 70 cm dipole antenna for MHz Both antennas made out of ½ inch wide spring steel measuring tape

Stanford (Sapphire) Four Transmitter Antennas Antennas made out of ½ inch wide tape measure. The antennas are all different lengths. One Receiver Antenna /4 monopole whip antenna
