Electromagnetic Coupled Circularly Polarized Hybrid Antenna for LTE Applications

In this communication, a hybrid antenna is presented with Circular Polarization (CP) for Long-Term-Evolution (LTE-2600 MHz) applications. The proposed hybrid-antenna is composed of a hexagonal-shaped patch loaded with a hexagonal-split-ring slot and a parasitic rectangular dielectric resonator block. Electromagnetic (EM) coupled-feed (Proximity-Coupled-feed) used to feed the antenna structure. A hexagonal split-ring has been etched diagonally at 45 degrees on the hexagonal patch to obtain the CP-radiation. By loading parasitic rectangular Dielectric-Resonator (DR) block along the edge of the patch, the Return Loss (RL) bandwidth, Axial Ratio (AR) bandwidth, and AR beam-width enhanced without disturbing the CP radiation. The performance of the proposed hybrid antenna versus split-ring slotted hexagonal patch is analyzed and discussed in this paper. The gain obtained for the proposed antenna is 6.75 dBic.
