Design of a Circular Slot Antenna with Broadband Dual CP Bi-directional Radiation Pattern

Design of a miniaturized Circular Slot Aerial with Broadband Dual CP with Bi-Directional Radiation pattern is anticipated. This aerial consists of a moon shaped opening to accomplish superband CP performance. Dual number of 50 ohms micro strip line ended with a half-moon arrangement ports to realize both RHCP and LHCP in the specified bandwidth. The ARBW is expressively increased by introducing cutting slot in the ground arrangement and shifting the input excitation to little offset from the full moon slit. The projected aerial is simulated. The simulated RL of -10dB is about (0.75~14.0 GHz) band and 0.65~6.45 GHz (ARBW of 3dB) and the S₂₁>24.25dB within the ARBW.
