In this article, a mixed split quadrilateral multiband microstrip antenna is designed and its measurement results in terms of different parameters are given. This patch antenna is designed to support modes with resonances at 6.3, 7.1, 7.5, 8.7, 12.8, 17, and 21.3 GHz. FR‐4 (lossy) is used as substrate to design the recommended antenna which has a firm dimension of 11 × 15 mm 2 (0.23λ × 0.31λ). This antenna operates at C, X, Ku, and K band with moderate bandwidth because of its design and feedline. This mixed quadrilateral‐shaped multiband antenna has directivity gain of 1.65, 1.26, 2.4, 3.2, 4.57, 4.03, and 3.46 dBi at resonating frequencies and is suitable for a modern communication system. The proposed split multiband quadrilateral antenna results are obtained in terms of return loss, voltage standing wave ratio (VSWR), gain, and radiation pattern which have admissible values of return loss less than −10 dB, VSWR less than 2 at each resonant frequency, and gain more than 3 dB. A suitable radiation pattern and an emerging gain make the recommended antenna suitable for the use in a modern communication system.
