How to Achieve High Gain in FRP Antennas
Fiberglass Reinforced Plastic (FRP) antennas are widely favored for their
excellent durability and signal performance. Their high gain, a key advantage,
is achieved through several sophisticated technical approaches:
Sleeve Dipole Design
Existing technologies adopt sleeve dipoles to realize wide-band, high-gain
FRP omnidirectional antennas. This design effectively concentrates signal
energy, enhancing the antenna's ability to transmit and receive signals over
longer distances while maintaining stable performance across a broad frequency
range.
Series or Parallel Feed Arrays
A common method to boost antenna gain is using series-fed or parallel-fed
element arrays. By increasing the radiation aperture of the antenna through
array configuration, the gain is significantly improved. Series-fed antenna
arrays feature a simple structure, though the beam direction may shift with
frequency changes, affecting performance when operating away from the center
frequency. Parallel-fed arrays, on the other hand, offer more stable beam
characteristics across frequencies.
Bilateral Linkage and Surrounding Linkage Components
Some high-gain 5G communication FRP antennas are equipped with bilateral
linkage mechanisms, surrounding linkage components, and detection modules. These
components automatically adjust the antenna to the optimal position for
receiving and transmitting 5G signals in multiple directions and angles,
effectively enhancing signal strength and improving communication gain.
Internal Component Optimization
In 858-930MHz high-gain FRP antennas, the design of internal components
plays a crucial role. This is particularly evident in applications such as
private network connections and ultra-long-distance fixed-point links, where the
optimized internal structure ensures efficient signal transmission and
reception, expanding the antenna's application scope.
Copper Tube Internal Structure
Many high-gain FRP antennas utilize copper tubes as part of their internal
structure. This design contributes significantly to improving gain performance
by reducing signal loss and enhancing the antenna's ability to focus and radiate
signals effectively.
