Design Of Cylindrical Conformal Array Antenna Based On Microstrip Patch Unit

Based on microstrip patch antenna, a cylindrical conformal 8x8 array antenna is designed, which uses a T-shaped power divider to realize 64 feed channels. The simulation results show that the peak gain of planar array antenna can reach 24.8dB, while the peak gain of cylindrical conformal antenna decreases by 1.2dB and 1.7dB in phi=0 degrees and phi=90 degrees respectively. And the main beam direction deflects by 0 degrees and 4 degrees respectively. The measurement results show that the performance of the processed object is close to the simulation. After conformal with cylinder, the peak gain is 23.5dB, and the beam deflection is 4 degrees, which verifies the feasibility of the designed cylindrical conformal array antenna.
