The planar antenna has a dielectric substrate; an antenna main body portion including first and second antenna elements on first and second sides, respectively, of the dielectric substrate and functioning as a balanced antenna; a signal line portion including first and second feed lines on the first and second sides, respectively, and a coplanar line on the first side and formed by a signal line and the first ground conductors, the signal line connected to the first feed line; a second ground conductor on the second side and connected to the second feed line; and via holes connecting the first ground conductors to the second ground conductor provided at ends of edges of the first ground conductors facing the end of the signal line where the signal line connects to the first feed line, to allow the first and second feed lines to function as balanced transmission lines.

FRET measurement uses a FRET probe that includes a probe element X containing a donor fluorescent substance and a probe element Y containing an acceptor fluorescent substance and enables FRET to occur when the probe element X and the probe element Y approach to each other or bind together. The modulation frequency of laser light with which the FRET probe is irradiated is adjusted to an optimum modulation frequency that maximizes a difference between the phase difference of donor fluorescence emitted from the donor fluorescent substance with respect to intensity modulation of the laser light at the time when FRET occurs and the phase difference of donor fluorescence emitted from the donor fluorescent substance with respect to intensity modulation of the laser light at the time when FRET does not occur.
