DECT Antenna help needed

Dear all,
Can anybody give me some papers or design ideas for design of a printed DECT antenna(1750-1950MHz),Omnidirectional with 0DBi gain.
Return loss is -10dB.

Advance thanks

what about your communication distance?We usually design a F-antenna for 300~350m .

A dipole could work for you. You might want to consider an end feed. -15 dB s11 is not too hard to come by.

If you really want 4Π coverage that is a different problem and not trivial but a dipole is usually good enough to be considered omnidirectional.

Hi, Thansk for the reply.

Can you provide any reference designs or papers if avilable.
