A cross-slot coupled hexagonal dielectric resonator antenna for C-band applications
2017
Design of novel cross slot fed hexagonal dielectric resonator antenna (DRA) of dimension 20× 20 × 10 mm 3 having substrate of material FR-4 is presented in this paper. The proposed antenna has a frequency range of 6.60–7.14 GHz in C-band, which includes the INSAT transmission frequency (6.725–7.025 GHz). The design frequency here is taken as 6.855 GHz which is fit for the application of STM link 1 and also applicable for the advanced microwave scanning radiometer channels (AMSR-E) of the earth monitoring system aqua satellite. The concepts and design parameters of the proposed antenna is theoretically analyzed and experimentally verified. The hybrid mode HEM 111 is achieved by using a symmetric cross slot. The simulated impedance bandwidth and the radiation efficiency are found to be 7.88% and 93.7% respectively.
