Abstract

A microstrip-line feed simple design of modified rectangular slotted patch antenna is proposed for dual-frequency operation. The typical rectangular shape of the patch is reformed by integrating slots and extending the radiating patch to some extent for achieving desired resonance. With the optimized dimensions from numerical simulating software, the proposed antenna is printed on 1.905-mm-thick 40 × 40 mm<sup>2</sup> ceramic composite substrate with relative dielectric constant ε<inf>r</inf>-=-10.2. The experimental results confirm the bandwidths for S11 ≤-10 dB are of 780 MHz (1.13-1.91 GHz) and 1.22 GHz (4.83-6.05 GHz) with resonance frequency 1.48 and 5.61 GHz, respectively. The antenna prototype shows almost consistent and symmetrical radiation patterns with maximum gain of 3.42 and 4.37 dBi for lower and upper frequency band, respectively. On the basis of well-agreed simulated and measured results, adequate bandwidth, stable radiation, and acceptable gain performance make the antenna suitable for serving simultaneously in global positioning system and wireless local area network bands.
