AH-640

Description

Model AH-640 is a broadband linearly polarized

double ridged waveguide horn antenna designed

specifically for Electromagnetic Interference

testing. This antenna can be used for receive as

well as transmit applications for the frequency

range of 26.5 GHz - 40 GHz.

This antenna has a high gain; at least 23 dBi over

the entire frequency range. This antenna can

accept up to 5 Watts of input power at its termi-

nals in continuous mode in the applicable fre-

quency range for generating electromagnetic

fields.

The AH-640 Horn antenna has a K type connec-

tor which can mate with SMA type connectors.

The antenna is constructed using lightweight

aluminum with a corrosion resistant finish. The

oval rear plate has a 1/4" x 20 threaded hole for

mounting to the Com-Power AT-100 tripod.

The antenna is individually calibrated at 1 meter

and data and certificate of calibration will be

shipped with the antenna. The data will include

the antenna factor and antenna gain.

Application

The AH-640 was designed for EMC testing, but

it can also be used for antenna gain pattern

measurements, surveillance, and other applica-

tions. The wide frequency band makes the AH-

640 antenna suitable for sweep measurements,

reducing the need for antenna switching during

the test.

High gain reduces input power requirements to

achieve the desired field levels for immunity

testing and improves antenna sensitivity to low

level signals. During emissions testing the mea-

sured field strength can be calculated by adding

the antenna factor for the particular frequency to

voltage measured at the antenna output terminal.

For immunity testing, the input power require-

ment P in Watts to generate E electric field

strength in V/m at a distance D in meters can be

calculated by using the following formula:

P = E

x D

/ 30 x N

N = 10

(G/10)

G = 20 log F -29.79- AF

Where

N = Numeric Gain

G = gain in dBi

F = Frequency in MHz

AF = antenna factor in dB/m
