5 Commercial-in-Confidence ERA Document No: 14096/TR001 Isuue: 1 1. Introduction This document describes the laboratory and range measurements undertaken at ERA Technology on the 1.0 metre linearly polarised Ku band reflector antenna required to demonstrate the performance of the system. The reflector system consists of a circularly symmetric main reflector and a feed chain/subreflector combination supported at the apex of the main reflector. The subreflector is a ‘splash plate’ configuration and it is supported at the feed aperture by a dielectric cone. The feed chain includes a rotating joint for polarisation alignment and a two port Orthomode Transducer (OMT) providing orthogonally polarised transmit and receive functions simultaneously. The back port of the OMT is the transmit port and the side port of the OMT is the receive port. The mounting of the feed chain/subreflector combination at the apex of the main reflector supports the feed chain and subreflector and the design of this fixture ensures that the configuration can be precisely integrated with the main reflector in the correct manner. The Test Plan and procedures undertaken at ERA are consistent with IEEE Standard Test Procedures for Antennas ANSI/IEEE Std 149-1979. 2. Objective The objective of the Tests is to measure the radiation patterns and gain of the 1.0 metre reflector antenna at Ku band operating in linear polarisation. 3.

Measurements 7.1 Introduction Measurements of antenna radiation patterns and gain were undertaken using ERA's 220 metre far field test range. The range comprises a remotely controlled primary transmitter unit and a receive facility located in a purpose-built test tower 15 metres in height. The receive facility is equipped with programmable Scientific Atlanta positioners, receivers and automatic data logging equipment. The transmitter site is furnished with a series of transmit points to cover the various bands. For Ku band the transmitter is a reflector about 900 mm diameter and it utilises a linearly polarised feed chain. The transmitter can be rotated around its axis to align the polarisation as required. Detailed surveys of this test range have been carried out in the most commonly used microwave bands that indicate co-polar reflectivity better than -50 dB and cross-polar isolations better than 55 dB.

The return loss measurements were swept frequency over 10.95 – 12.75 GHz and 13.75 – 14.5 GHz, whilst isolation was measured over 10.95 – 14.5 GHz. The following were measured: i) Return loss at Rx and Tx ports. ii) Port-to-port isolation. When measuring the return loss, the unused port was terminated in waveguide load and for all measurements the reflector was radiating into free-space or suitable anechoic shield.

12 Commercial-in-Confidence ERA Document No: 14096/TR001 Isuue: 1 Typical measurement accuracy after 12-term vector error correction can be read directly from graphs provided by the analyser manufacturer for reflection coefficient and transmission loss. The errors are Root-Sum-Squares (RSS) calculations of the contributions of residual directivity, load and source match, frequency response, isolation, network analyser dynamic accuracy and connector repeatability. This gives: i) Return loss of 20 dB : Uncertainty (Reflection coefficient) =0.017 dB (RSS) ii) Return loss of 15 dB : Uncertainty (Reflection coefficient) =0.019 dB (RSS) Table 4: Laboratory Measurements Frequency Figure Measurement Return loss Rx Band 10.95 – 12.75 GHz Figure 3 ≤ -17.6 dB Return loss Tx Band 13.75 - 14.50 GHz Figure 4 ≤ -18.6 dB Isolation Tx - Rx 10.95 - 12.75 GHz Figure 5 > 35 dB 13.75 - 14.50 GHz Figure 6 > 37 dB 7.4 Antenna Range Measurements 7.4.1 Introduction The procedures undertaken at ERA are consistent with IEEE Standard Test Procedures for Antennas ANSI/IEEE Std 149-1979. The measurements were undertaken using a linearly polarised Ku band transmit source. The antenna under test (AUT) was installed on the positioner and the mixer connected to the relative antenna port. 7.4.2 Pattern measurements procedure For antenna pattern measurements: i) Select the frequencies; co-polarise the transmitter with the AUT and steer the AUT to receive maximum signal. Set azimuth and elevation indications to zero. ii) Rotate the required axis and record the co-polar pattern. iii) Rotate transmitter polarisation by 90° and record the cross-polar pattern.

13 Commercial-in-Confidence ERA Document No: 14096/TR001 Isuue: 1 iv) Repeat for other frequency bands. All the measurements were taken by rotating in azimuth. For the elevation cut measurements, the AUT was rotated by 90° and the measurements taken with the AUT rotated in azimuth. Patterns were taken ±180o or a narrower limited range with the angular increment 0.5o or less, as described in the Range Measurements Plan, Section 7.4.5. 7.4.3 Gain measurements procedure and results The antenna gain measurements were performed by comparing with a commercially available linearly polarised Standard Gain Horn (SGH): i) Locate Standard Gain Horn (SGH) on antenna mount. ii) Select frequencies; co-polarise the transmitter with the AUT and steer the AUT to receive maximum signal. Set azimuth and elevation indications to zero. iii) Record the co-polar signal from the AUT. iv) Record the signal from the SGH. v) Repeat iii) and iv). The AUT gain will be determined by the average of the two measurements taken. Table 4 gives the gain computations.

Table 6: Far field Range measurement uncertainties Parameter Value Mutual Coupling 0.0 dB Tx Amplitude Taper (0.25 dB) 0.1 dB Reflections (Elevated Range) 0.01 dB Frequency Stability 0.01% Power Level < ± 0.05 dB Standard Gain Horn ± 0.25 dB Spacing Tx to AUT 0.01 dB Tx isolation 0.01 dB Total RSS (Root-Sum-Square) 0.27 dB The overall accuracy of the gain measurements undertaken using a commercial Standard Gain Horn is estimated to be ±0.27 dB. 7.4.5 Range measurements plan The Test Plan for the range measurements is given in Table 7. All the measurements were recorded by rotating in azimuth. The elevation cut measurements were recorded by rotating in azimuth after turning the AUT by 90°. Since the AUT is linearly polarised, the cuts in Table 7 are identified as E-plane or H plane cuts. For example, for a vertically polarised antenna, E-plane is the elevation cut and H-plane is the azimuth cut. Co-polar and cross- polar component patterns were be taken for ±180o in θ, the angular increment 0.5o. Co-polar and cross-polar measurements were taken for ±22.5o in θ with the angular increment 0.05o. All the measurements were recorded as ASCII text files in amplitude (dB). The data were then processed in Excel spreadsheets in the format required by Anatel and were supplied with the Test Report. The recorded patterns are included in this Test Report and identified by the Pattern Number as given in Table 7. Ref: 14096/TR001   © ERA Technology Ltd
