I have designed Pyramidal horn using 2 methods
(c.a banalis)
i) as pe=ph to be physically reliable are these values acceptable
ii) how to calculate flare angles?
2nd method
Design and Testing of Pyramidal Horn MBR Murthy; M.Sudhakar; B. Lokeswara Rao* Professors, Department of ECE, CMR College of Enginnering & Technology, Hyderabad 501401, Telangana, India.
re=rh has very small difference in this calculation
iii) Also used adk cal. match nearly with 2nd method
iv) Is it necessary that flare angle are needed to be equal in h and e plane?
iv) i want to fabricate it but adk gives direct excitaion to wave guide i want to use connector Sma/ or N how to place them in hfss ?
(c.a banalis)
- f = 1.2 GHz λ = 25 cm
- g=13 db
- χ 0.7
- a 19.56 cm
- b 9.78 cm
- pe 17.5
- ph 24.3
- a1 42.1 cm
- b1 29.6 cm

vi) i want to scale down aperture lengths a1 and b1. how it can be done?
Helppp ..!!!!!!!!
