Randtron Antenna Systems has thoroughly exploited the flared notch antenna as an element of large antenna arrays. The flared notch antenna is a single element, which can be printed or constructed of solid metal. The antenna is capable of large bandwidths (greater than 3:1) and the solid metal element is capable of handling large amounts of high power. The flared notch array was developed at Randtron Antenna Systems by our engineers for radar and communications applications. Because of its broad beamwidth, the flared notch element is an ideal element for electronic scanning antenna arrays requiring moderate bandwidth and power. A recent development for communications involved a three-band antenna array. The K-band and S-band arrays use flared notch elements to provide linear polarization, while a patch antenna is used to develop circular polarization at L-band. Flared notch antennas can be used in a crossed configuration to provide dual circular polarization by constructing the elements in an "egg-crate" fashion. A polarization quadrature hybrid is required to generate the time phasing. The construction can be modified for low-cost fabrication using printed circuit techniques.

When an antenna with wide angle electronic scanning, wide bandwidth, and high power capacity is needed for your radar or communications requirement, call on Randtron Antenna Systems to see how a flared notch antenna can be utilized in your application.
