Orqa FPV.P1 5.8GHz Patch Antenna (RHCP)

The RF design of P1 is finely tuned so that the optimum range is exactly between 5.65GHz and 5.97GHz, with the best results between 5.7GHz and 5.9GHz, and peak performance at 5.8GHz (5.803 GHz, to be exact).

We have aimed to achieve exceptional VSWR with a solid cross-polarisation attenuation. VSWR is a proxy to power transmission efficiency (how well the antenna delivers the RF energy to the receiver), and cross-polarisation attenuation tells us how resilient antenna is to radio pollution from the multipath wave propagation (reflections of the original signal) and cross-polarisation transmitters (radio sources transmitting on the opposite polarisation).

At 5.803GHz, the P1 measures an exceptional VSWR of 1.174 with a very good level of worst-case cross-polarisation attenuation of 15dB. Between 5.7GHz and 5.9GHz, the VSWR is well below 1.2 with good cross-polarisation attenuation; towards the edges of this band, VSWR goes even below 1.1, but with weaker attenuation compared to 5.803GHz. Across the entire optimal frequency range, P1 measures VSWR within the limits of the optimal range (below 1.4).
