  1. in the simulation I achieved 14dBi. This brim is shallower than the simulation assumes, it could be 11.3 dBi. The antenna is very effective. I'm thinking of replacing the quadrates with loops. I'm thinking of a similar implementation as in the attached pictures, not laminate. @Harry36 Thank you for the clarification. With this antenna I am receiving ham radio beacon beacon SR6 LHZ 1296.830 with level -80dBm - distance 111 km, power 1W My aim is to increase the gain of a single biquad. maybe changing the shape or geometry will help. That is my antenna:
  2. I am thinking of using bi-loop instead of biquad, I use matlab on a daily basis, and I have not yet managed to make a model, I am currently unable to check 1) Bi-Loop is mechanically simpler to make, tune and correction. What else, what profit can it give. In publication about this antenna for a 2,45GHz: "The simulation results showed that the best parameters value are 14.95 mm of loops radius, 1.15 mm of links radius, and 15.57 mm of reflector gap. In these parameters, the antenna had a characteristic value of return loss -36.65 dB, bandwidth 354 MHz" IMG_1496.webp
