摘要： In an electromagnetic coupling type four-point feeding loop antenna (10) comprising a tubular body (11), a loop portion (12) having a loop width (W1), four feeders (13) each having a feeder width (W2), and four electromagnetic coupling wires (17) each having a coupling wire width (W3), the loop width, the feeder width, and the coupling wire width are substantially equal to one another. A gap (&dgr;) between the feeder and the electromagnetic coupling wire is laid in a range between 0.2 mm and 0.8 mm, both inclusive, when the electromagnetic coupling type four-point feeding loop antenna has a feeding impedance of a range between 25 &OHgr; and 100 &OHgr;, both inclusive.

摘要： To provide a circularly polarized antenna capable of obtaining an excellent axial ratio over a very wide range and having a great gain in a zenith direction. The circularly polarized antenna (10) includes a planar loop antenna element (122) and feeding means for providing quadruple feeds with their phases varied by 90 degrees with respect to the planar loop antenna element (122). The feeding means has four feeding probes (131 through 134). The circularly polarized antenna (10) is provided with a circuit board (25) disposed in parallel with the planar loop antenna element (122). The circuit board (25) has an area greater than that of the planar loop antenna element (122). The circuit board (25) has a principal surface (25U) which entirely serves as a ground plane. The circuit board (25) has a rear surface (25L) provided with a 90-degree phase shifter formed thereon.
