AWID's ANT-867CP-0.5 is optimized for (EU) frequency band 863-869MHz. Optimization results are positive realized gain, low axial ratio of radiation and high return loss over operational frequency band achieved within small volume with linear size less than 1/4 of wavelength.

Features

• Maximum achieved realized gain and frequency bandwidth within small volume.
• Variation of the Maximum Gain is less than ±0.27dB in Z direction at any Phi angle within operational frequency band.
• Variation of the Maximum Gain is less than ±0.5dB within frequency band 859-876MHz at the fixed Phi angle.
• It provides low reflection of the transmitter signal into receiver. The return loss is more than 18dB.
• Extremely light – weight is 20g or 0.7oz.

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, which guaranties the stability of tag interrogation at any position.
• Size, weight and gain of the antenna are optimized for handheld applications.
• Antenna may be adopted for installation into various plastic enclosures with minor correction of the tuning components.
