The presentation
Satellite relays and amplifies the radio telecommunications signals via transponder. It creates communication channel between transmitter and receiver. Antennas, along with the transponders are the key to satellite communication. Antennas affixed to satellites play an important role in transmitting and receiving the signals. Most of the currently used Antennas are made of metals, these will become lossy at high frequencies, and Microstrip Antennas, these are limited with narrow band width. To overcome these limitations, The Di-electric Resonator Antenna (DRA) model is proposed. These types of antennas have wide bandwidth and lower losses at high frequencies. It is the block of a di-electric material mounted on a surface. They are easy to integrate. The gain, bandwidth, and polarization characteristics of a DRA can be easily controlled using different design techniques. There are many shapes of DRA. The main advantage of the rectangular DRA is that it is characterized by three independent geometrical dimensions, i.e. Length, Width & Height. These three parameters individually varied to resonate the antenna in the required frequency. A Rectangular DRA with probe feed is proposed, designed & simulated works in the frequency of 1.621 GHz for satellite communication. It is an on-board Antenna. Type of feeding is Probe Feeding. This DRA has a bandwidth of 260 MHz. The required polarization for this antenna is RHCP (Right Hand Circular Polarization). This model is designed & simulated in CST Microwave Studio and analyzed under FDTD (Finite Difference Time Domain) & FEM (Finite Element Method). The antenna parameters like Return loss, VSWR, Impedance Plots, Gain and Radiation patterns are recorded and compared in both FDTD & FEM. Simulation results in both the cases are matching above 90%, this boosts confidence of the designer
