A Wideband Co-Linearly Polarized Composite Antenna with High Isolation
(2024) In IEEE Antennas and Wireless Propagation Letters 23(1). p.419-423- Abstract
In this paper, a high-isolation two-port co-linearly polarized (co-LP) composite antenna is proposed. Dipole and W8JK array modes with co-LP omnidirectional patterns can be simultaneously supported by a plate with two etched back-to-back tapered slots. A microstrip differential and a T-divider coupling feeding networks are developed to selectively excite the dipole and W8JK modes, which results in a high isolation and low correlation between two co-LP ports without using any decoupling structures. Reflecting ground is applied to realize the directional radiation. Measurement results show that the overlapped operating band of the antenna can cover 3.4 - 4.1 GHz with low measured envelope correlation coefficients (< 2.5... (More)

A microstrip differential and a T-divider coupling feeding networks are developed to selectively excite the dipole and W8JK modes, which results in a high isolation and low correlation between two co-LP ports without using any decoupling structures. Reflecting ground is applied to realize the directional radiation. Measurement results show that the overlapped operating band of the antenna can cover 3.4 - 4.1 GHz with low measured envelope correlation coefficients (< 2.5 × 10-3) and high isolation (> 20 dB). Dual-polarized four-port element with good performances can be easily obtained based on the proposed co-LP antenna. The simulated results of the four-port prototype indicate that the proposed antenna is a promising candidate for the future compact massive MIMO array antenna.
