Abstract :
A compact 7 × 7 flat lens antenna design for X-band applications is presented in this paper. A new design with aperture-coupled E-shaped patch elements at 10 GHz is simulated and analyzed. This antenna design is realized by using two back-to-back printed patches with slotted common ground plane and feed horn antenna. The transmission loss obtained of 2.2 dB is sufficiently low. A 320° transmission phase range for the E-shaped patch unit cell is achieved with less than 1.5 dB of deviation in the transmission loss level.The proposed design uses a simple technique and less manufacturing complexity for transmission phase control.
