Abstract :
We consider three models of compact wideband microstrip antennas (MSA) with radome to operate in the frequency range 1.2 to 1.65 GHz. They are characterized by different forms of ring-radiating patch and a weak capacitive coupling with the feeder microstrip line. Each antenna has a suspended substrate FR4 with radiator patch and feed strip and a lower substrate FR4 with the microstrip line and broadband transition from the microstrip line to the feeder strip.
