Hybrid elliptic TEM horn with symmetric main beam

A 3‐D Printed PCB Integrated TEM Horn Antenna

“…A Transverse ElectroMagnetic horn antenna based on the transition and the 90 • bend presented above is designed following a published design procedure (Malherbe, 2012; see Figure 10). The aperture of the antenna is 42 × 30 mm 2 and its length is L a = 85.5 mm.…”

Exponential TEM horn with a convex triangular arc

“…identical directivity vs. θ performance for all values of φ) is difficult to achieve over similar bandwidths. The improvement of the radiation properties of these horns has been the topic of various papers over the years, most recently by Malherbe who uses specialised plate width and plate separation functions [1], [3], and vertical ridges in the horn [2] respectively, and Hradecky [4] using dielectric lenses. An interesting variation which replaces the straight edge of the horn with a curved arc (in this case a concave arc) was introduced by Karshenas et.…”
