Abstract :
An easy estimation of the gain enhancement of a microstrip patch that occurs when a standard PTFE substrate is replaced by air is presented. The theory is verified for a wide range of antenna dimensions, using some measured and simulated data, indicating very close agreement amongst the data. This approach should be very handy and useful to a designer dealing with air-substrate microstrip antennas.
