Actively and passively excited sinusoidal microstrip and PCB strip antennas operating at K and millimeter-wave bands

Abstract Actively and passively excited sinusoidal wire structure is applied to the PCB strip and microstrip structures successfully at K and millimeter‐wave frequency bands. Antenna dimensions are reduced till the half value, and more rigid structure is also obtained than the sinusoidal wire antennas by this way. Actively excited PCB sinusoidal antennas are investigated at these high frequencies and passively excited ones are introduced in the literature for the first time in this study. Transversely polarized broadside radiation is obtained for both types of antenna. The measured field patterns are compared with the calculated and simulated ones. The calculated patterns, phase velocity, and attenuation constants of investigated antennas are calculated by a written MATLAB code based the analytical approach. © 2008 Wiley Periodicals, Inc.
