The wideband microstrip antenna with capacitive feed with the low level of the VSWR
, 2018 Antennas intended for onboard radio systems with a limited power reserve must have a small the VSWR. This is due to the fact that the smaller the VSWR of the antenna, the greater the radiated power (at a fixed input power) and the longer the radio range (
