Is it a planar coil or with round conductors? Whats your application? There are actually some papers out there which investigated best inner/outer diamter ratio and spacing between turns
How is your design going ? I've done quite a lot of designs in this area. There are some good books on amazon. But the main criteria is that you should develop for high Q at resonance frequency. Whats your design frequency ? Feel free to PM me
Hi
Short question:
I have an upcoming design with 1 lora modem which supports 868 and 915 bands. The antenna I will use supports 868 and 915 MHz bands
The problem is the pi matching network needs to be designed to either 868 or 915 (according to antenna datasheets). Any workarounds to have a...
Hi,
I have a project where a antenna is needed
Requirements:
The antenna must fit in this enclosure: **broken link removed**
Attention points:
PCB with ground plane inside enclosure
Batteries under PCB (=metal)
Requirements
High efficiency
Operational on 868MHz ISM band
Is there anyone who...
Hi all!
A normal dipole has a gain of 1.6dBi..right ?
This stacked dipole has a a gain of 9dBi:

but its kinda big....
I want to design a compact high gain antenna with the use of meta material as...
