Similar to the Elliptical edge-fed circularly polarized patch, this new antenna is fed with a pin-feed. Its expected performance is similar to the edge-fed variant as well as the Pin-fed notched circular patch. The pin-fed variant is smaller than the edge-fed variant because of the space used by the quarter wave transformer. For higher impedance patches, the pin-fed variant can be designed on a wider range of substrates (where the matching section of the edge-fed patch becomes too thin at higher impedances).
Unlike the Pin-fed notched circular patch, Antenna Magus can design the Elliptical pin-fed circularly polarized patch for input impedance.
