Microstrip antennas suffer from low gain bandwidth product due to surface wave effects and aperture diffractions that limit their use for long-range communications.
On top of that, the difficulty of achieving a pure circularly polarized radiation with high gain due to the feeding structure effects.
This paper is subjected to design a gain enhanced circularly polarized patch antenna using Uniplanar Compact-Photonic Band Gap (UC-PBG) structu.res for UHF RFID applications.
The patch is structured as truncated corners with cross slots at the centre mounted on an FR-4 epoxy substrate of 1.6mm thickness with an overall area of 188×188mm2.
The UC-PBG is constructed of two layers; each is made of 7×7 unit cells, separated by 20mm mounted from the top of the patch at 30mm height.
The unit cell characterizations are evaluated in terms of their S-parameters and dispersion diagram CST-MWS environment.
The antenna shows a boresight gain of about 8.2 dBi at 915MHz with a front to back ratio (F/B) of 13dB.
The benchmark enhancement in boresight gain after adding the UC-PBG layers is found to be 3.4 dBi with a radiation efficiency of 87%.
Finally, an excellent agreement is achieved between the obtained measurements and numerical results.
