| Summary: | This paper presents a compact and planar, in-band full-duplex antenna that offers significant isolation across a broad range of frequencies. In order to attain a wide impedance bandwidth within a limited physical space, two half-resonating modes of a microstrip patch antenna (MPA), namely TM<inline-formula> <tex-math notation="LaTeX">$_{\mathrm {0,3/2}}$ </tex-math></inline-formula>and TM<inline-formula> <tex-math notation="LaTeX">$_{\mathrm {1,1/2}}$ </tex-math></inline-formula>, are stimulated in close proximity. Moreover, the utilization of a parasitic strip that acts as a <inline-formula> <tex-math notation="LaTeX">$\lambda $ </tex-math></inline-formula>/2 resonator, assists in increasing the inter-port isolation. A prototype is fabricated and further measurements indicate that the proposed design offers inter-port isolation better than 30 dB across its wide operating band of 5.95-6.47 GHz, which corresponds to approximately 9% impedance bandwidth (<inline-formula> <tex-math notation="LaTeX">$\vert $ </tex-math></inline-formula>S<inline-formula> <tex-math notation="LaTeX">$_{11}\vert $ </tex-math></inline-formula>, <inline-formula> <tex-math notation="LaTeX">$\vert $ </tex-math></inline-formula>S<inline-formula> <tex-math notation="LaTeX">$_{22}\vert \lt -10$ </tex-math></inline-formula> dB). Additionally, the prototype exhibited a significant peak gain of 8.2 dBi. |
