AbstractA low profile compact microstrip antenna for GPS (L1/L2) application has been
presented in this paper. The proposed antenna design is based on the 3rd iteration
Minkowski-like pre-fractal geometry. The resulting antenna design offers a compact size,
low profile and light weight making it suitable for use in handheld applications. Antenna
performance has been evaluated using the EMSightTM from the Applied Wave Research.
The proposed antenna has shown to possess two resonance bands (for return loss .-10
dB) covering the two GPS bands. Reasonable radiation characteristics have been achieved
at the GPS frequencies (L1:1575.42 } 10.23 MHz, L2:1227.60 } 10.23 MHz) with good
circular polarization characteristics. Realized circular polarization Bandwidths (for axial
ratio . 3 dB) are found to cover adequately those required for these GPS bands.
