This paper presents a triple band microstrip electromagnetic band gap (EBG) patch antenna with two shaped parasitic elements used for 2nd and 3rd mode excitation, permitting multiple band resonance and control of the resonance frequencies. Simulation and measurement results show triple-band (S/C/X-band) antenna applications that can effectively cover three separate bandwidths: 3.79 GHz for moderate range surveillance, terminal air traffic control, long-range weather, marine radar; 7.5 GHz that satisfy the requirements of the C-band applications specific for long-distance radio telecommunications; 11.8 GHz that satisfy the requirements for X-band applications destined for satellite communications, radar, terrestrial broadband, space communications, amateur radio, molecular rotational spectroscopy. The main characteristics of the proposal is its ability to increase the gain, directivity, return loss and the total efficiency of the antenna without affecting the geometric parameters, which makes the designed antenna applicable for a wide range of radio frequency devices operating at the chosen resonance frequencies. The simulated results using computer simulation technology 2014 compared to experiment have demonstrated attractive performance such good impedance matching, compact features (light weight, small sized, low cost), and rigidness compared to other classic antennas.
