spe - 11 - 8 - 1 30 / e /ss page 2 of 9 i introduction the wpc.25a 2.4ghz cerami c patch antenna with cable works on wi - fi, zigbee, bluetooth and ism band at 2.4ghz. this antenna comprises of a 2.4ghz 25*25*4mm embedded patch with mini - coax cable and connector for connectivity and a pcb carrier to mount the antenna. the wpc.25a is circ ularly polarized which is more suitable to avoid interference and phase cancellation from reflections. the antenna has its own ground pcb carrier and is therefore ground independent. ii specification wi - fi frequency ( m hz) 2400~2500 peak gain (dbi) > 0.5 a verage gain (dbi) > - 2.5 efficiency (%) > 50 impedance 50? polarization rhcp input power 10 w mechanical dimensions 25*25* 5.5mm cable type 1.37 mini coaxial cable cable length 150 mm connector ipex mhf1 environmental temperature range - 40c to 85c humidity non - cond ensing 65c 95% rh
