Our Experience
With years of combined experience in the design, manufacturing and testing of antennas, JEM's engineering team is able to develop working solutions for its customers. JEM's engineering team's depth of experience continues to expand by working with high profile customers including the U.S. Navy, NASA and Applied Signal Technology. See below for a snapshot of some of JEM's success stories and contract work:
 |
Type of Customer: |
Government and Commercial |
| Type of Antenna: |
Dual polarized patch antenna |
| Frequency: |
18.5–19.5 GHz |
| Application: |
Designed for a communications data link application (medium range backhaul) |
| Details: |
The antenna incorporates two arrays with orthogonal polarizations for transmitting and receiving. It operates at 18.5–18.7 GHz and 19.5–19.7 GHz; the two 64-element sub-arrays each achieve 24 dBi gain. Antenna is supplied with a radome and adjustable mount for wall or tower mounting. |
 |
Type of Customer: |
Government and Commercial |
| Type of Antenna: |
Bicone Antenna |
| Frequency: |
27 GHz |
| Application: |
Designed to function as the base station transmit antenna for a 27 GHz point-to-multipoint communication system |
| Details: |
The antenna features an omni-directional 10 dBi gain over the 26.5–27.5 GHz band with a 10 W RF power handling capability. Antenna is supplied with a radome and mount for outdoor installation.
|
 |
Type of Customer: |
Government and Commercial |
| Type of Antenna: |
Symmetric Genetic Antenna |
| Frequency: |
2–18 GHz |
| Application: |
Designed for an unattended ground sensor for radar detection |
| Details: |
The antenna has a symmetric vertically-polarized monopole-like pattern across the frequency range. The antenna is small (<1.5" tall), and since the radiator is made from wire, it is efficient, lightweight and cost effective. Antenna is supplied with a radome and groundplane. |
