The design of slot‐coupled, reduced‐size triangular microstrip antennas with a shorting‐pin or chip‐resistor loading is described. The fundamental mode of TM 10 is studied. Impedance matching can be achieved simply by adjusting the coupling‐slot size, with the slot center fixed at the null‐field point of the TM 10 mode, and the required slot size increasing with increasing loading resistance. The case with a chip‐resistor loading also shows a lower resonant frequency and a significantly enhanced operating bandwidth, as compared with the shorting‐pin loading case. Details of the experimental results are presented and discussed. © 1997 John Wiley & Sons, Inc. Microwave Opt Technol Lett 16: 371–374, 1997.
