AWID's ANT-915CA2x2 is optimized for frequency band 902-928MHz.

Optimization results are high realized gain, very low axial ratio of radiation and high return loss over operational frequency band.

Features

• Maximum achieved realized gain and frequency bandwidth within moderate volume.
• Variation of the Maximum Gain is less than ±0.18dB 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 886-953MHz at the fixed Phi angle.
• It provides very low reflection of the transmitter signal into receiver. The return loss is more than 23dB.
• Light – weight is 3480g or 123oz.

Benefits

• The antenna is intended for application with RFID mono-static interrogator architecture and it provides better interrogation rate and range because of very low VSWR.
• Antenna provides uniform electromagnetic field within narrow cone, which guaranties the stability of tag interrogation at any position in required direction.
• High realized gain and low VSWR increase the interrogation range for semi-passive RFID tags at reduced transmitter power.
• Size, weight and gain of the antenna are optimized for stationary applications.
• It may be employed for indoor and outdoor installations with IP66 rating.
