AWID's ANT-915CPD is optimized for frequency band 902 - 928MHz in a Bi-static architecture. However, it may be employed in a mono-static architecture with multiple RF ports to improve interrogation in multipath fading condition.

Features

• Maximum achieved realized gain and frequency bandwidth within moderate volume.
• Variation of the Maximum Gain is less than ±0.88dB in Z direction at any Phi angle within operational frequency band.
• Variation of the Maximum Gain is less than ±0.5dB within the frequency band 876 - 973MHz at the fixed Phi angle.
• Very low coupling of the transmitter signal into receiver. The isolation is more than 29dB.
• Moderately light weight - 943g or 33.3oz.

Benefits

• The ANT-915CPD antenna is intended for applications with RFID interrogator architecture with separate transmitter and receiver RF ports to provide better interrogation rate and range.
• It provides uniform electromagnetic field, which guaranties the stability of tag interrogation at any position.
• Size, weight and gain of this antenna are optimized for stationary applications.
• It may be employed for indoor installations.
