We have developed a new type of balun, called "photonic balun", to receive the balanced component of a RX antenna. Because the photonic balun is connected to a receiver through an optical fiber, we can realize an ideal antenna measurement free of unwanted effects of a coaxial cable. To demonstrate the superiority of the photonic balun in antenna measurements, we compare the vertical polarization...
We have developed a new type of balun (photonic balun) for measuring characteristics of receiving antennas operated in balanced mode below about 2 GHz. The photonic balun consists of a photonic sensor with resistors in an aluminium box whose size is 2 cm times 2 cm times 4 cm. The common-mode rejection ratio is below -30 dB and Sdd of the differential mode is less than 0.2 below 1 GHz. From the pattern...
