15.3.4.5. 2600130021 - Himalia - 2.4 GHz dipole antenna

Figure 25: 2.4 GHz dipole-antenna

Due to the fact, that the antenna has dipole topology there is no need for an additional

ground plane. Nevertheless the speciﬁcation was measured edge mounted and 90° bent on

a 100 x 100 mm ground plane.

Speciﬁcation Value

Frequency range [GHz] 2.4 – 2.5

Impedance [Ω] 50

VSWR ≤ 2:1

Polarization Linear

Radiation Omni-Directional

Peak Gain [dBi] 2.8

Average Gain [dBi] -0.6

Efﬁciency 85 %

Dimensions (L x d) [mm] 83.1 x 10

Weight [g] 7.4

Connector SMA plug

Operating temp. [°C] -40 – +80

Special care must be taken for FCC Certiﬁcation when using this external antenna to fullﬁl

the requirement of permanently attached antenna or unique coupling for example by using

the certiﬁed dipol antenna in a closed housing, so that only through professional installation

it is possible to remove it.
