Product Details
The MPAX is a narrowband microstrip patch antenna built to a custom center frequency anywhere from 3.5 to 8.5 GHz, specified at the time of order. Two gain options are available: the MPAX-L, a single-element patch with typical gain of 6 dBi and a broader beam, and the MPAX-H, a multi-element patch array with typical gain of 10.5 dBi and a narrower beam. Both are linearly polarized, built on high-quality PTFE microwave laminate to minimize loss, and offered with an optional water-resistant enclosure and multiple mounting options. Every antenna is guaranteed to meet its published specifications at the requested frequency, and ships with individually measured VSWR, radiation pattern, and boresight gain data.
- Custom-tuned to any center frequency from 3.5 to 8.5 GHz, specified at order; guaranteed to meet spec at your frequency or your money back.
- Two gain options: MPAX-L single-element patch (typ 6 dBi) or MPAX-H multi-element array (typ 10.5 dBi).
- Linearly polarized, 50 Ω, SMA female; handles up to 10 W of input power.
- Built on high-quality PTFE microwave laminate to minimize loss; optional water-resistant enclosure with multiple mounting options.
- Individually measured VSWR, radiation pattern, and boresight gain provided with each order; raw data (.txt/.s1p) available on request.
- Suited to fixed-frequency point-to-point links, radar and sensing, test and integration, and embedded systems.
