What are the 4 main factors discussed to consider when making an antenna selection
Microstrip patch antennas commonly use four feeding methods: edge feeding (50Ω impedance matching with λ/4 transformer), probe feeding (1-2mm diameter pin at optimal 30-40% patch length), aperture coupling (1-3mm slot with 1-2dB lower cross-polarization), and proximity coupling (2-5mm overlap for wider bandwidth up to 15%). Each method balances bandwidth (2-5% vs 10-15%), complexity, and spurious […]
