Question about ble antenna

Hi, I'm routing pcb with cc2541 + cc2590 and I have a question. Can I use "CC2590EM reference design" impedance matching circuit but change only antenna from IFA (like in design DN007) to meandered IFA (AN043)? The board stack is the same (4 layers, widths, lengths etc...). As I understand both antennas have 50 Ohms impedance, but I'm not quite experienced in RF to conclude that antennas are equivalent.


Thanks
