WLAN Directional Panel Antennas with Superior Gain and Small Size

A new series of compact directional panel antennas for wireless local area network (WLAN) applications over the 2.4 GHz industrial, scientific and medical (ISM) band has been introduced that features a patent-pending printed circuit design. The antennas offer wideband coverage from 2300 to 2500 MHz and superior gain flatness vs. frequency.

The new WLAN directional panel antennas are available in three models with either connectors or pigtail connections. The models MP24008, MP24011 and MP24013 antennas offer gains of 8, 11 and 13 dBi, respectively (7.7, 10.7 and 12.7 dBi for the pigtail versions), with SWRs of 1.4 or less (1.5 for the pigtail models). The MP24008 antenna includes a female SMA bottom-feed connector; the other two models are available with female TNC bottom-feed connectors. All models may be obtained with a 12" RG58/U pigtail option and a choice of a wide variety of cable connectors. The antennas feature vertical or linear polarization that may be adjusted with an optional model MPAB mount.

The antennas also feature a UV-stable off-white ASA-ABS radome design with a weather-resistant black-powder-coated aluminum back plate that may be custom painted to blend in with the antenna’s surroundings. The water-resistant, low profile enclosure makes the units suitable for both indoor and outdoor applications, and their low 1.1" profile provides minimum visibility and blends well in office environments.

Fig. 1 The model MP24011 panel antenna's (a) vertical and (b) horizontal radiation patterns All WLAN directional panel antenna models operate over the frequency range of 2300 to 2500 MHz, handle greater than 50 W of RF input power and are designed to operate from -51° to +71°C. Table 1 lists other electrical performance parameters for the various antenna models. The antenna is DC grounded for lightning protection. Wind loading for the MP24008, MP24011 and MP24013 models is 9.3, 17.5 and 27.9 lb, respectively for 100 mph wind. The MP24008 antenna is housed in a compact 5.0" x 4.6" x 1.4" package and weighs 0.22 lb. The MP24011 measures 8.7" x 4.9" x 1.4" and weighs 0.44 lb, and the MP24013 measures 8.7" x 7.9" x 1.4" and weighs 0.77 lb. Figure 1 shows the MP24011 antenna’s typical vertical (elevation) and horizontal (azimuth) radiation patterns.

Mounting hardware includes a clamp set (the adjustable mount is sold separately). List prices for the model MP24008, MP24011 and MP24013 panel antennas are $99.98, $147.72 and $163.31, respectively. The optional MPAB mounting bracket, interface plate and hardware for the panel antenna are priced at $39.82. Similar panel antennas are also available for the 800 to 900 MHz, PCS and wireless cable frequency bands.
