This article proposes the design of microstrip patch antennas to improve low‐elevation gain for controlled reception pattern antenna (CRPA) applications. The proposed antenna consists of a main resonant patch and a subpatch that are electromagnetically coupled with each other to operate as a two‐element array whose bore‐sight direction points toward low‐elevation angles. The array factor is then enhanced by inserting a ceramic substrate with a high dielectric constant to maximize the electrical distance between the patches. As a result, the average gain at θ = 75° is enhanced by 1.2 dB, which demonstrates that the proposed antenna is suitable to be used for the individual elements of CRPA arrays with the improved radiation gain at low‐elevation angles. © 2016 Wiley Periodicals, Inc.
