“…4 was printed on a Roger Duroid RO4003C microwave substrate of 0.813 mm thickness and relative permittivity of 3.38. These values are then substituted into other design equations stated in [3], [4] to determine the values of interdigital capacitance C, strip inductance L, and the pad capacitances C p1 and C p2 ; and finally obtain the desired resonance frequency f 0 of the design using (4) of [4]. QLER offers a high degree of design freedom and flexibility.…”

This paper presents a 6-element series array quasi-lumped element resonator antenna. The proposed antenna employs an interdigital capacitor in parallel with a straight strip conductor whose center finger is shorted across the capacitor. An array configuration is imperative as the gain of a single quasi-lumped element arrangement was only moderate and specifically put at about 9.4 dBi which may not be adequate for long distance communications. Relevant Equations for radiation pattern of the quasilumped element resonator (QLER) were derived and presented. The proposed antenna array exhibits a gain enhancement up to about 29.47% with a noticed size reduction of 80 × 30 sq. mm. Compared to standard long wire antenna and other approaches of capacitive loaded long wire antennas, it was proved that the proposed antenna has a relatively better performance yet with significant size reduction. Consequently, it is an ideal candidate for MMIC designs and wireless communication applications.

“…When the size of the antenna is reduced, the single-element provides low value of directivity as a result of reduced radiative resistance. This leads to the problem of decreased radiative efficiency as the ratio of the antenna conductor to the radiated power decreases as frequency increases [2], [3].…”
