The Antenova guides have been informative and I'm concerned the overall size of our board is too small for a ceramic antenna. We are developing an IOT device on a 70mm x 70mm PCB with the usual array of components, including several SMT sensors, microprocessor, LTE transceiver, GNSS/GPS receiver. The million dollar question is deciding between a PCB mount antennas (e.g. ceramic) or a thin flat style with short coax and UFL plug. We're working with the standard LTE and GNSS (L1) frequencies. If it will work decently and be easily implemented (we have a small design budget) then going with the PCB mount antenna(s) are the first choice to reduce cabling, mounting, assy, etc. There is about 20mm x 50mm of area for the antenna and a component free zone. Does this seem reasonable for a board of this size to get fair to good performance? Is it unrealistic to think an onboard antenna can be implemented without dozens of hours of tuning, tweaking, designing?
