3/25/2005 Coho Diversity 6.5 dBi Patch Technical Specification 1. Introduction This document describes the set of specifications for a diversity patch antenna to be used in the 2.4 GHz band. The basic features of this antenna are as follows: • Directional antenna for indoor/outdoor operation • RP-TNC Connector with 3-ft of plenum rated, cold temperature capable cable. • Operates over the entire 2.4 GHz band. • Peak gain is around 6.5 dBi In general, this antenna will be housed in a white polycarbonate radome very similar to the Coho AIR-ANT2485P-R except that there will be two cables. It will be built with 3 feet of off-white plenum rated cable and terminated in an RP-TNC. The specifications for this antenna will be presented sequentially with Electrical Specifications first, followed by Mechanical/Environmental Specifications and General Specifications. 2. Physical Appearance The actual antenna inside the radome is expected to be built on a fairly large ground plane of about 110 mm x 165 mm (3.94 in x 6.5 in). This large ground plane size allows for the placement of two patches over the same ground plane as well as the use of a simple radome that fits over the ground plane rather than use two pieces of plastic to form the enclosure. This will lend itself to a rectangular radome of about 110 mm x 165 mm x 25 mm. The actual antennas will be arranged on the ground plane as shown in Figure 2.1. The radome has not been designed at this time. Figure 2.1 Simulated Model of AIR-ANT2465P-R A printed version of this document is an uncontrolled copy. Cisco Systems, Inc.

3/25/2005 Coho Diversity 6.5 dBi Patch Technical Specification 3. Diversity 6.5 dBi Patch Antenna Specification This section contains both the electrical and mechanical specs for the Coho diversity 6.5 dBi patch antenna. Basically, this package contains two patch antennas built with an air dielectric over a ground plane. The antenna will have 3 feet of white/off-white plenum rated coaxial cable capable of operating down to -30 C. 3.1. Antenna Electrical Specifications and Patterns The electrical specifications for this antenna are summarized in Table 3.1.1 below. H- and E-plane patterns are shown in Figures 3.1.1.and 3.1.2. Note that the patterns shown include all cable losses as well as the losses associated with a hand built radome.

There are two antennas housed in a single radome, each with its own feed cable. Each patch is built with an air dielectric over the ground plane. Each patch is 11 Construction 40 mm W x 51 mm L and is formed from a single piece of brass. The ground plane is 110 mm x 165 mm and is built from 2.6 mm thick aluminum. The patches are placed 7 mm above the ground plane. 110 mm x 165 mm 12 Size (4.3 in x 6.5 in) Table 3.1.1 Coho 6 dBi Patch Antenna, Electrical Specifications A printed version of this document is an uncontrolled copy.
