A compact design of rectangular microstrip patch antenna (RMPA) is presented for its improved cross-polarized (XP) radiation properties. This is achieved by suppressing the spurious higher-order modes of the patch. In here, the non-radiating edges of the patch are partially shorted to the ground plane through metal stubs. This enables a design technique without perturbing the radiating patch or the ground plane. About 16 dB suppression of XP radiation in the H plane has been achieved without disturbing the co-polarized peak gain value. The spurious higher-order mode has been eliminated. The proposed design has been validated experimentally using a set of fabricated antenna prototypes. Measured results are nicely corroborated with the simulated data.
