Regardless of the application, all microwave communication systems are faced with transmission line matching problem, related to the load or impedance connected to them. The mismatching of microwave lines with the load connected to them generates reflected waves. Mismatching is identified by a parameter known as VSWR (Voltage Standing Wave Ratio). VSWR is a crucial parameter on deter- mining the efficiency of microwave systems. In medical application VSWR gets a specific importance. The presence of reflected waves can lead to the wrong measurement information, consequently a wrong diagnostic result interpretation applied to a specific patient. For this reason, specifically in medical applications, it is important to minimize the re- flected waves, or control the VSWR value with the high accuracy level. In this paper, the transmission line under dif- ferent matching conditions is simulated and experimented. Through simulation and experimental measurements, the VSWR for each case of connected line with the respective load is calculated and measured. Further elements either with impact or not on the VSWR value are identified.

Thanks to the HE’s compact size, they Diameter (0.35") are ideal for internal concealment inside a product’s housing. The HE is also very low in cost, making it well suited to high-volume applications. HE Series Inside 6.4 mm Diameter (0.25") antennas have a very narrow bandwidth; thus, care in placement and layout is required. In addition, they are not as efficient as whip-style antennas, so they are generally better suited for use on the transmitter end where attenuation is often required Wire 15.24 mm Diameter (0.60") anyway for regulatory compliance. Use on both 1.3 mm 6.35 mm transmitter and receiver ends is recommended only (0.05") (0.25") in instances where a short range (less than 30% of whip style) is acceptable. 38.1 mm (1.50") Features • Very low cost • Compact for physical concealment Recommended Mounting • Precision-wound coil No ground plane or traces No electircal • Rugged phosphor-bronze construction under the antenna connection on this • Mounts directly to the PCB pad.

  • Slotted Line-SWR
    Lab 2: Slotted Line and SWR Meter NAME NAME NAME Introduction: In this lab you will learn how to characterize and use a 50-ohm slotted line, crystal detector, and standing wave ratio (SWR) meter to measure an unknown impedance. The apparatus used is shown below. The slotted line is a (rigid) continuation of the coaxial transmission lines. Its characteristic impedance is 50 ohms. It has a thin slot in its outer conductor, cut along z. A probe rides within (but not touching) the slot to sample the transmission line voltage. The probe can be moved along z to sample the standing wave ratio at different locations. It can also be moved into and out of the slot by means of a micrometer in order to adjust the signal strength. The probe is connected to a crystal (diode) detector that converts the time-varying microwave voltage to a DC value with the help of a low speed modulation envelope (1 kHz) on the microwave signal. The DC voltage is measured using the SWR meter (HP 415D). 1 Using Slotted Line to Measure an Unknown Impedance: The magnitude of the line voltage as a function of position is: + −2 jβ l + j(θ −2β l ) jθ V ()z = V0 1− Γe = V0 1+ Γ e with Γ = Γ e and l the distance from the load towards the generator. Notice that the voltage magnitude has maxima and minima at different locations. + Vmax = V0 (1+ Γ ) when θ − 2β l = π + Vmin = V0 (1− Γ ) when θ − 2β l = 0 V 1+ Γ The SWR is defined as: SWR = max = .

O. Otasowie* and E. A. Ogujor Department of Electrical/Electronic Engineering University of Benin, Benin City, Nigeria. Accepted 8 September, 2009 In this work, Voltage Standing Wave Ratio (VSWR) was measured in a Global System for Mobile communication base station (GSM) located in Evbotubu district of Benin City, Edo State, Nigeria. The measurement was carried out with the aid of the Anritsu site master instrument model S332C. This Anritsu site master instrument is capable of determining the voltage standing wave ratio in a transmission line. It was produced by Anritsu company, microwave measurements division 490 Jarvis drive Morgan hill United States of America. This instrument works in the frequency range of 25MHz to 4GHz. The result obtained from this Anritsu site master instrument model S332C shows that the base station have low voltage standing wave ratio meaning that signals were not reflected from the load to the generator. A model equation was developed to predict the VSWR values in the base station. The result of the comparism of the developed and measured values showed a mean deviation of 0.932 which indicates that the model can be used to accurately predict the voltage standing wave ratio in the base station. Key words: Voltage standing wave ratio, GSM base station, impedance matching, losses, reflection coefficient. INTRODUCTION Justification for the work amplitude in a transmission line is called the Voltage Standing Wave Ratio (VSWR).

    A “Refresher” on VSWR • VSWR stands for “Voltage Standing Wave Ratio” sometimes abbreviated as just SWR. • The subject is appropriate for all types of transmission lines. • Note: If the transmission line is much less than λ / 4 , then the analysis of “transmission line transformers” and possibly “baluns” is more appropriate. Transferring Power in Transmission Lines • For maximum power transfer, the impedance at the load end of the line must be matched to the transmission line’s characteristic impedance. ZL= Zo Transmitter Tuner CHARACTERISTIC IMPEDANCE = Zo Transmission Line Characteristic Impedance • Characteristic Impedance Z o is Resistive. • Z o is fixed by the geometry of the conductors. µo • Impedance of “free space” Zo = = 376.73031Ω εo Parallel Wires Typical values: 200Ω to 800Ω Coaxial Cable • Most common values, Z o = 50Ω, and 75Ω Typical values: 25Ω to 100Ω Mismatched Transmission Line • Energy reaching the load will not be fully absorbed. • Some of the energy is reflected back toward the source by the “impedance discontinuity.” • Splicing two transmission lines of different impedance will also cause a reflected wave.
