Hi, In classical dipole,loop antennas I will say yes that's the cause that people prefers to use baluns(altough antennas are not my specialitzation), another feasible option depending on your operation frequency will be the use of antennas printed on your PCB(I think a kind of it that allows differential feeding is called 'bowtie'), of course you then need to use something like differential coplanar lines(GND RF+ GND RF- GND) between your IC and the antenna(and probabaly you must do the design of the antenna with a magnetic simulator), I also have read some papers that directly they are integrating(or trying to integrate) the antenna inside the IC(but at frequencies above 20GHz due to the area reduction with increasing frequency). Hope it helps,
