Bottom line up front: successful prototype, need help designing a smarter-looking remote control but my RF knowledge isn’t up to scratch.
I built a prototype remote control for a project using bog-standard 433 MHz RF Tx. The antenna is a simple 17cm monopole copper wire coming out the back of the Tx ANT pad. Driven by a 9V battery and a Micro plus inputs.
I’d like to now make a better version, using the Atmega as-is and placing it buttons and all on a smart-looking PCB, epoxied and on display. I plan to place the RF Tx flat against the PCB and connect the ANT to a nearby SMA and 1/4L stub antenna via a trace as shown in the pic.
My question is, will this work, and if not, what other ideas are there to make an attractive device rather than a bare-wire antenna?
