The influence of antenna gain and beamwidth used in OSSEUS in the screening process for osteoporosisApplications on electromagnetic waves in the field of biotelemetry have increased in the latest years, being used to prevent, diagnose, and treatment of several diseases. In this context, biotelem...
Antenna gain [7] is the most important parameter in the design of an antenna system. A high gain is achieved by increasing the aperture area, A, of the antenna. Antennas obey reciprocity; the transmit gain and receive gain are the same, and the antenna can be analyzed by examining it ...
Many of the radar system properties are directly related to antenna characteristics and performance. As you can see from the equation, the range of the radar increases with the square of the antenna gain and decreases with the antenna loss. We’ll talk about gain a lot more later, but it ...
天线增益AntennaGain 天线增益 与由理想的全向天线(各向同性天线)在各 个方向所产生的输出相比,天线增益定义为 在一特定方向上的功率输出 有效面积Effectivearea 与天线的物理尺寸和其形状相关 天线收益AntennaGain 天线增益与有效面积的关系表达为: G=天线增益 A e =有效面积 f=载波频率 c=光速(约等于3×10 8 ...

Design a reflector at 1 GHz with the dipole as the exciter and FR4 as the substrate. Get rf = reflector(Exciter=d,Spacing=7.5e-3,Substrate=t); rf.GroundPlaneLength = lambda_d; rf.GroundPlaneWidth = lambda_d/4; figure show(rf) Remove the groundplane for plotting the gain of the ...
The sidelobes can be improved with tapering the gain across elements and will be the subject of an upcoming section in this series. The beamwidth reduces with the number of elements. The beamwidth widens as the beam is scanned away from boresight. The number of nulls increases as the ...
