I would start with clear idea about what I’d like to do, than simulate using some of the simulation tools and after I have confirmed my idea is OK I’ll continue with hardware and programming the microcontroller.
There are a number of questions you have to consider about. The frequency, broadband or not, gain, polarization, suitable dimensions, environmental conditions, application …
All of those parameters could lead you to the answer about the right antenna for you.

Basically, all the clocks in reality are non-ideal one. There are at least two effects which could be observed by non-ideal clock. First one is the fast instability of clock which is described primarily as phase jitter causing phase fluctuations in the circuits we design. The second one is long...
As far as l knows, most of the waveguide to coax transitions are so designed that it covers the whole frequency range of the waveguide primary mode of propagation. Design of such transition isn’t to complex, and no special design process is needed. If there is need for really special transition...
First of all, you have to use some kind of antenna to catch the RFID signal on 134 kHz. You may use air antenna of about 50 windings of wire (0,5 mm diameter) on the suitable holder with dimension of about 20-30 cm diameter (not necessary to be round). Ends of the antenna you may connect to...
