This paper describes the performance and construction of several multi
band integrated microstrip antennas around 35 GHz on in-house semi-ins
ulating multilayer GaAs, The simulated and measured input impedances a
nd radiation patterns at both the lower and upper resonant frequencies
are given and some experimental results are provided to check the acc
uracy of the electromagnetic simulations.
