Evaluation of Gain Measurement Method for Long Antenna Using Synthetic Aperture Antenna
A cellular base station antenna has a narrow beam width in the vertical plane because the length of the antenna is more than 10 λ. While generally long distance measurements are needed to measure the antenna with high accuracy, some measurement methods in a short-range anechoic chamber have been used. The compact range method [1-2] and near-far field transformation method [3-6] are very popular...
متن کاملMethods for Measuring Rf Radiation Properties of Small Antennas
In this work significant improvements for measurements of the radio-frequency (RF) radiation properties of small antennas have been proposed and investigated. The main focus is on electrically small antennas as used in mobile communications systems. The methods proposed and evaluated in this thesis allow the minimisation of the dimensions of measurement chambers, and the methods also allow patt...
متن کاملImproving the Performance Parameters of Microstrip Patch Antenna by Using Ebg Substrate
The objective of this paper is to analyze the performance of electromagnetic band gap (EBG) antenna for base station applications through simulation. The proposed analysis is carried out using the high frequency structure simulator (HFSS). In our method, to overcome several intrinsic limitations of patch antennas such as constrict bandwidth, low gain, excitation of surface waves, the EBG concep...
متن کاملEcho Identification and Cancellation Techniques for Antenna Measurement in Non-Anechoic Test Sites
This paper focuses on the measurement of antenna radiation patterns when fully anechoic conditions are not available and, as consequence, some undesirable echoes are initially present in the measure. Two techniques are analyzed and compared, which -starting from data measured in the frequency domain -allow the echo contributions to be identified and the antenna radiation pattern to be retrieved...
متن کاملDevelopment of an Enhanced Gain Substrate Integrated Waveguide H-plane Horn Antenna Using Thin Substarte
In this paper a dual band and high gain H-plane horn antenna implemented by substrate integrated waveguide (SIW) using a single layer thin substrate is introduced. The proposed antenna consists of five parts of rectangular waveguide with different width arranged in a staircase manner to allow mode combination of fundamental and higher propagating modes of the structure. By adjusting the length ...
