Abstract

A coplanar waveguide (CPW)-fed monopole as a radiating element of an active antenna amplifier is proposed for chip size realization. A monopole antenna, which is integrated with a high electron mobility transistor (HEMT), demonstrates stable oscillations at a frequency of around 5.8 GHz within a 10% bandwidth of 580 MHz (from 5.58 to 6.16 GHz). The active antenna has dimensions of 9 mm times 8 mm times 1.3 mm. The measurement results show that the antenna effective isotropic radiated power (EIRP) is +10.5 dBm, power added efficiency (PAE) 30.3%, and the phase noise at 100 kHz offset -88.3 dBc/Hz.
