Radar Reflectivity of Micro Rain Radar (MRR2) At 16.44180N, 80.620E of India

To improve accurate standards of Radar Reflectivity Z, Rainfall Rates RR, and even to monitor small size precipitation particles Z-R relation is derived in this work with the help of Micro Rain Radar. Formerly, taking rain/precipitation data from ground-based rain gauges (Cylindrical, Optical, Weighing, Tipping Bucket Rain Gauges, Disdrometers, etc.,) currently, in this work using METEK MRR (Micro Rain Radar) of Frequency Modulated Continuous Wave System which reads the vertical structure of precipitation particles and hence named as vertical profile radar which operates at 24.2 GHz and height up to 6000m/6kms with an increment step size of 200m respectively to monitor the frozen hydrometeors. It is installed at (16.440 N, 80.620 E) K L University, 29 meters above the sea level (ASL) in CARE LAB. To know the Radar Reflectivity of precipitation, it is observing the amount of power received to the radar receiver after hitting the precipitation particles with respect to the transmitted power of the radar. This proposed work considered distinctive rain conditions at different heights ASL ranging from 200m 1200m 2200m, and derived Z-R relations respectively

Analysis of CSRR Based Circular Patch Monopole Antenna for Ku-band Satellite Communication Applications, C-band and X-band Applications

In this paper, a circular patch monopole antenna with circular CSRR slots is presented for WiMAX applications. The proposed antenna contains circular polarized patch with circular CSRR slots. Smaller triple-band antenna is planned by drawing CSRR slots on the radiating component. It is seen from the outcomes that the proposed antenna can be utilized for satellite communication application. In order to verify high separation between adjacent components, the circular patch monopole antenna array of the proposed antenna element is also manufactured and tested in order to make the proposed antenna a possible candidate to be incorporated into satellite communications. Utilizing this strategy, a changed circular monopole are proposed and examined as the plan model. Both estimated and reproduced results are given and talked about to confirming the legitimacy of proposed plan procedure. In an ordinary lab climate, the injurious multi-way transmission impacts on the exchange capacity of the model receiving wire pair were noticed and talked about. This streamlining procedure would not carry any size or cost increment to the printed monopoles, and the improvement of transmission execution is very detectable, which has all the earmarks of being a critical improvement over printed UWB monopoles.The antenna delivers maximum peak gain of 8.27 dB at 13.9 GHz.The proposed antenna with the dimensions of 26231.6. The estimated results: radiation pattern, peak gain, radiation efficiency is showing the good results. The proposed antenna can be utilized for C-band (4.2, 7.6 GHz), 5.5 (HYPERLAN) X-band (9.7 and 11.4 GHz) and Ku-band (13.9 GHz) satellite communication applications

Parasitic Strip Loaded Dual Band Notch Circular Monopole Antenna with Defected Ground Structure

In this article a parasitic strip loaded monopole antennas are designed to notch dual and triple bands. The designed models are constructed on one side of the substrate material and on the other end defected ground structures are implemented. The basic antenna comprises a tuning stub and a ground plane with tapered shape slot as DGS. Another model is constructed with circular monopole radiating element on front side and similar kind of ground structure used in the basic rectangular tuning stub antenna. To create notched bands with tuning stubs, two symmetrical parasitic slits are placed inside the slot of the ground plane. The basic model is of the rectangular stub notching triple band and the circular tuning stub antenna notching dual band. Dual band notched circular tuning stub antenna is prototyped on FR4 substrate and measured results from vector network analyzer are compared with simulation results of HFSS for validation
