Performance Analysis of Microstrip Antenna Using GNU Radio with USRP N210

Abstract: Radiation pattern and power spectrum measurements become inevitable while analysing performance of an antenna. Current test bench for these measurements are considerably costly. In this paper, the performance of microstrip antenna is evaluated using GNU (GNU is Not Unix) Radio companion (GRC) and Universal Software Radio Peripheral (USRP). The radiation pattern obtained is used in the measurement of Half Power Beam Width and Front to Back Ratio of the antenna. In addition to these measurements, received signal power is also calculated using the Frobenius norm method. Finally, the economic advantage of the proposed method is compared with conventional measurements.

Method for monitoring electrical performance parameters of base station antenna

Abstract: The invention discloses a method for monitoring electrical performance parameters of a base station antenna The method comprises the following steps: adopting an HackRF One hardware platform to receive electromagnetic waves emitted by the base station antenna, and performing intermediate frequency processing and digital processing on the electromagnetic waves; transmitting processed data to an Android system terminal, and performing digital filtering processing and FFT processing on the data, and obtaining spectral analysis; and finally finishing extraction of the electrical performance parameters according to the spectral analysis, wherein the electrical performance parameters comprise the half-power beam width, side lobe level, front to back ratio, directivity factor, and antenna gain The method for monitoring the electrical performance parameters of the base station antenna provided by the invention optimizes the accuracy of a traditional extraction method of the electrical performance parameters; and the monitoring method is helpful to help the base station maintenance personnel to maintain antenna equipment, optimize the network, and improve the stability and reliability of interactive data between a mobile terminal user and a base station

High front -to -back ratio base station antenna reflecting plate

Abstract: The utility model relates to a mobile communication field, more specifically relates to a high front -to -back ratio base station antenna reflecting plate, this high front -to -back ratio base station antenna reflecting plate, including reflection face (1), the setting is at the left and right sides curb plate (2) of reflection face both sides, the setting is at the cavity structures of reflecting plate downside, the setting is in metal sheet extension structure (4) in the cavity structures bottom outside, reflection face (1), left and right sides curb plate (2), cavity structures and metal sheet extension structure (4) mutual formula structure as an organic whole, the utility model discloses a high front -to -back ratio base station antenna reflecting plate through the setting of controlling curb plate, cavity structures and metal sheet extension structure, makes high front -to -back ratio base station antenna reflecting plate have outstanding front -to -back ratio, and this antenna design is more succinct, has reduced the assembly, and the cost is practiced thrift in the production of being convenient for.

Front to Back Ratio Improvement in Microstrip Antenna Array Using AMC for LTE Applications

Abstract: This paper aims to present an antenna array with Artificial Magnetic Conductor (AMC) surface that operates at the frequency of LTE Band 5 (869 MHz to 874 MHz). In this work, three different prototypes designed and analyzed to improve the front to back ratio of microstrip antenna. First prototype is a single patch microstrip antenna, second prototype is its 2×1 array and in third prototype an AMC is used as ground plane of the array. The final prototype offers 35.79% improvement in the front to back ratio. The simulated results have also been experimentally validated.
