Microstrip ultra-wideband antenna measurements

New microstrip ultra-wideband antenna is presented and measured in this paper. The antenna was calculated to operate in 3.1-10.6 GHz ultra-wideband frequency band, even though the measurements revealed that it covers the band 3.4-12 GHz. It's manufactured on the basis of Rogers RO4350B, which is appropriate for this band. Antenna's total size with SMA connector 72970 Pomona is 39 mm × 19 mm. The main goal stated in this paper is to prove the antenna's characteristics, simulated before, by carrying out full-time measurements in anechoic chamber. Particularly the return loss, VSWR, transfer function, input impedance and radiation pattern were measured and analyzed, which finally showed similarity of simulation and measured results. It can be announced that the antenna has very wide radiation pattern (more than 180°) and well-matched to 50 Ohm in the entire frequency band. Since it's small, compact, low profile it can be applied in many modern high-capacity communication systems, including UWB, hybrid optical fiber-wireless networks, 3G and future 5G networks.
