Abstract In this paper, a new cavity-backed antenna configuration, called strip, slot, air, inverted patch (SSAIP) is proposed. The SSAIP is the cavity-backed version of the standard strip, slot, foam, inverted patch (SSFIP) antenna concept, and this paper compares the electrical performances of both types of antennas. Chapter 4: Broadband Microstrip Antennas | Engineering360 The use of a groundplane slot excited with a microstrip line which in turn couples to a microstrip patch can be adjusted to produce an elegant matching network which provides a broadband input impedance match.

The use of a groundplane slot excited with a microstrip line which in turn couples to a microstrip patch can be adjusted to produce an elegant matching network which provides a broadband input impedance match. One implementation of this type of antenna is called SSFIP for Strip Slot Foam Inverted Patch by Z rcher and Gardiol in the mid 1990s A wideband strip-slot-air-inverted patch antenna array The antenna can be named SSAIP (strip-slot-air-inverted patch) as it used air instead of foam. To minimize the cost and substrate losses, 3 mm air is used as an upper layer above the ground. The use of air is more low-priced than using low loss foam material. In addition, the porous nature of foams makes it sensitive to moisture.
