Circularly polarised rectangular Bi-Quad

Image of the Circularly polarised rectangular Bi-Quad.

The Circularly polarised rectangular-Biquad antenna is similar to the standard bi-quad antenna in terms of size and performance. The feed of the Circularly polarised rectangular-Biquad antenna differs from the classical Biquad feed, in that the two arms are driven against each other (in the same way that a dipole or bowtie would be fed). This antenna is very simple to construct and performs well over a moderate frequency band with up to 10 dBi gain.
