The primary advantage, over standard loop antennas, is the wide frequency band performance, as well as the ability to make the antenna smaller than standard size.
About
A physical design improvement that offers wide frequency band performance in loop antennas, allowing operation with a voltage standing wave ratio of less than two (VSWR <2). The general shape employs two unequal ellipses, the feed region is kept wide and the grounded end kept narrow. Additionally, this design can operate as either a full-loop or half-loop and operate with systems of specific characteristic impedance. The antenna can be backed with or without a substrate to adjust performance.
Key Benefits
The primary advantage, over standard loop antennas, is the wide frequency band performance, as well as the ability to make the antenna smaller than standard size. The design can operate as a half or full loop, and pieces of the surface conductor may be removed to change radiation characteristics. Excellent radiation patterns for omnidirectional coverage.
